Application In Synthesis of 2-(Dimethylamino)ethyl acrylate

ExamplesThe foregoing may be better understood by reference to the following example, which is presented for purposes of illustration and is not intended to limit the scope of the invention.A pilot plant unit was assembled to demonstrate the process and to obtain comparative data. Using the process equipment described above, the process was repeatedly executed in successive experiments. Each experiment used a specific set of conditions and was run for a period of time long enough to reach steady-state conditions. In addition to sampling the final product, an in-process sample was also taken from the lower portion of the CSTR by means of a dip-tube installed in the CSTR, in order to observe the physical state of the reaction mixture in the lower portion of the reactor at any given time.The final product was analyzed for the impurities acrylic acid (AA), N,N-dimethylaminoethyl acrylate (DMAEA), and N,N-dimethylaminoethanol (DMAE). The level of acrylic acid impurity in the final product is commonly measured to give an indication of the level of acrylate ester hydrolysis over the course of the entire process. Also measured were the total amine impurities (DMAEA+DMAE), which indicate the total level of TAS present in the final product. These amine impurities are primarily generated in the CSTR or reaction section of the process, where they arise from hydrolytic side reactions that ultimately form DMAEA and DMAE salts that are unreactive towards the desired quaternization reaction. We have discovered that the amount of these total amines (DMAEA and DMAE) is an important indicator of the quality of the final product, as these amine impurities cause the final product to be unstable towards polymerization during processing and storage.As shown in table 1, control runs 1 and 4 gave unacceptably high levels of residual acrylic acid and unquaternized amine impurities. In contrast, run 11 provided extremely low levels of unquaternized amine impurities in the final product, while also providing low levels of acrylic acid impurity. Runs 9 and 10B, provided reasonably low levels of acrylic acid and unquaternized amine impurities in the final product, but the impurity levels were higher than those provided by run 11.

The synthetic route of 2-(Dimethylamino)ethyl acrylate has been constantly updated, and we look forward to future research findings.

Chemoselective Union of Olefins, Organohalides, and Redox-Active Esters Enables Regioselective Alkene Dialkylation

Multicomponent catalytic processes that can generate multiple C(sp(3))-C(sp(3)) bonds in a single step under mild conditions, particularly those that employ inexpensive catalysts and substrates, are highly sought-after in chemistry research for complex molecule synthesis. Here, we disclose an efficient Ni-catalyzed reductive protocol that chemoselectively merges alkenyl amides with two different aliphatic electrophiles. Starting materials are readily accessible from stable and abundant feedstock, and products are furnished in up to >98:2 regioisomeric ratios. The present strategy eliminates the use of sensitive organometallic reagents, tolerates a wide array of complex functionalities, and enables regiodivergent addition of two primary alkyl groups bearing similar electronic and steric attributes across aliphatic C=C bonds with exquisite control of site selectivity. Utility is underscored by the concise synthesis of bioactive compounds and postreaction functionalizations leading to structurally diverse scaffolds. DFT studies revealed that the regiochemical outcome originates from the orthogonal reactivity and chemoselectivity profiles of in situ generated organonickel species.

Characterization of the Volatile Components of Essential Oils of Selected Plants in Kenya

Essential oils are secondary metabolites that plants produce for protection from pests and predators, attraction of pollinators, and seed dispersal. The oils are made up of a mixture of compounds that give a characteristic flavour and odour. Currently, essential oils are receiving great attention in research for their phytochemical and antimicrobial activities. However, there is scanty information on the chemical composition of many plants. This study provides a detailed analysis of the chemical composition of essential oils of ginger, garlic, tick berry, and Mexican marigold in Kenya. The essential oils were extracted by steam distillation and analysed by gas chromatography-mass spectrometry. The study identified a total of 52 different chemical classes from the essential oils of the four different plants that were analysed. Their percentage composition was also found to vary between the test plants. The essential oils of Mexican marigold constituted the highest composition of the identified chemical classes at 71.2%, followed by ginger at 55.8%, while both tick berry and garlic oils constituted 53.8% of the total classes identified. Terpenes constituted the highest composition in the essential oils of all the four test plants. Other major chemical classes included esters, ketones, organosulfurs, alkanes, cycloalkanes, steroids, aromatic hydrocarbons, and alkanols. Some of these chemical compounds have been shown to have a huge utility potential in biopesticides, pharmaceutical, and food industries, and hence, their industrial extraction and purification from the essential oils of these plants are recommended.

The impact of different Saccharomyces cerevisiae strains on microbial composition and quality of Chinese rice wine fermentations

Chinese rice wine (CRW) is a popular fermented product in China, with complicated microbial composition and flavour compounds. To reveal the effects of different strains of Saccharomyces cerevisiae (N85 and XZ11) on the microbial composition in the process of brewing, metagenomic sequencing approaches were carried out to explore the dynamic changes of bacteria and fungi. Furthermore, the volatile compounds and organic acids in CRW were identified by headspace solid phase microextraction (HS-SPME)/gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) at the end of the brewing. Our results indicated that different S. cerevisiae strains could influence microbial compositions and especially affected the growth of Lactobacillus brevis and Pantoea ananatis. The changes in the microbial community structure contributed to the remarkable difference in the content of lactic acid, esters, alcohols, and aldehydes. Moreover, functional network analysis provided insights into the biological correlations between microbial species and metabolic pathways, that is, Lactobacillus genus had negative effects on metabolic activities. This study expands the idea of improving the quality of CRW by controlling the microbiome.

Effects of flavourzyme addition on physicochemical properties, volatile compound components and microbial community succession of Suanzhayu

Flavourzyme is known to promote protein decomposition, resulting in more peptides and amino acids which can improve the quality of fermented foods. In this study, the effects of flavourzyme addition on the fermentation of Suanzhayu fish were investigated. The results showed that the addition of 50 U/g flavourzyme reduced the water activity (a(w)) of products and promoted the release of trichloroacetic acid (TCA)-soluble peptides and free amino acids (FAAs). Thus, the stability of the product was improved and its nutritional value was increased. In addition, with the addition of flavourzyme, Lactobacillus and Saccharomyces more quickly became the dominant genera in the fermentation. Furthermore, the formation of alcohols, aldehydes, and esters was promoted in flavourzyme addition group. Redundant analysis (RDA) indicated that Lactobacillus and Lactococcus play important roles in the formation of flavors, especially for the characteristic flavors of Suanzhayu. Flavourzyme addition may be a novel method to greatly improve the properties of Suanzhayu and shorten the fermentation time.

Effect of fuel injection strategies on the performance of the common rail diesel injection (CRDI) engine powered by biofuel

The effects of fuel injection strategies on the characteristics of common rail diesel injection engine using mahua methyl ester (MME20) blend have been investigated. Fuel injection strategies such as fuel pressure and split injection have been implemented on a test engine. When MME20 was used as the fuel on mechanical injection at an injection pressure of 22 MPa, specific fuel consumption and NOx emission were found to be increased and brake thermal efficiency (BTE) decreased. In the first phase, in order to optimise the utilisation of the mahua methyl ester blend, fuel injection pressure was increased from 20 to 50 MPa with an increment of 10 MPa. The experimental observation reveals that high fuel injection pressure (50 MPa) exhibits higher BTE and better combustion characteristics when compared with decremented injection pressures. HC, CO and smoke level decreased with an increase in injection pressure due to better-atomised spray and mixture formation. In the second phase, implementation of spilt injection 5% MME20 as pilot injection at 5 degrees, 10 degrees and 15 degrees CA before main injection was identified with the decrease of HC, CO, NOx and smoke emission with marginal sacrifice of BTE compared with diesel fuel.

Synthesis of Boronic Ester gamma-Lactam Building Blocks

Saturated heterocycles are found widely in biologically active compounds such as medicinal drugs and agrochemicals. However, boronic acid-derived building blocks for these structures have limited availability, particularly in comparison to heteroaromatic boronic acids. We report the preparation of boronic ester gamma-lactams through a Cu-catalysed conjugate borylation-cyclisation protocol. Using a chiral catalyst, this can be performed in high enantioselectivity. Exploration of the further transformations of these reagents suggest that the boronic esters have much potential as chemical building blocks.

Synthesis and cytotoxicity of (-)-homo-renieramycin G and its derivatives

(-)-Homo-renieramycin G and its twenty derivatives were prepared from l-tyrosine methyl ester via a multi-step route. Their cytotoxicities were tested against four human cancer cell lines (A549, HeLa, KB and BGC-823). (-)-Renieramycin G and (-)-homo-renieramycin G showed comparable cytotoxicity against these four cancer cell lines, which indicated that the expansion of ring C from the six-membered 1,4-piperazinone to the seven-membered 1,4-diazepanone had no obvious impact on the cytotoxicity. Compound 42 with methyl side chain and compounds 38-41 with heterocyclic aromatic side chains at C-23 exhibited the most potent cytotoxicity with the IC50 values at the level of 10(-6) M.

Derivatives of nitrogen mustard anticancer agents with improved cytotoxicity

In previous studies, we demonstrated that esters of bendamustine containing a basic moiety are far more cytotoxic anticancer agents than their parent compound and that the substitution of the labile ester moiety by a branched ester or an amide markedly increases stability in the blood plasma. In the current study, we showed that this substitution was bioisosteric. Aiming at increased cytotoxicity, we introduced the same modification to related nitrogen mustards: 6-isobendamustine, chlorambucil, and melphalan. The synthesis was accomplished using the coupling reagents N,N ‘-dicyclohexylcarbodiimide or 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethylaminium tetrafluoroborate. Cytotoxicity against a panel of diverse cancer cells (carcinoma, sarcoma, and malignant melanoma) was assessed in a kinetic chemosensitivity assay. The target compounds showed cytotoxic or cytocidal effects at concentrations above 1 mu M: a striking enhancement over bendamustine and 6-isobendamustine, both ineffective against the selected cancer cells at concentrations up to 50 mu M, and a considerable improvement over chlorambucil, showing some potency only against the sarcoma cells. Melphalan was almost as effective as the target compounds-derivatization only provided a small improvement. The novel cytostatics are of interest as model compounds for analyzing a correlation between cytotoxicity and membrane transport and for the treatment of malignancies.
