Zarini, Daniele published the artcileAre In Silico Approaches Applicable As a First Step for the Prediction of e-Liquid Toxicity in e-Cigarettes?, Product Details of C12H14O2, the publication is Chemical Research in Toxicology (2020), 33(9), 2381-2389, database is CAplus and MEDLINE.

Recent studies have raised concerns about e-cigarette liquid inhalation toxicity by reporting the presence of chems. with European Union CLP toxicity classification. In this scenario, the regulatory context is still developing and is not yet up to date with vaping current reality. Due to the paucity of toxicol. studies, robust data regarding which components in tent. In this study we applied computational methods for studied chems. as a useful tool for predicting the acute toxicity of chems. contained in e-liquids The purpose of t the potential health concerns associated with e-liquid ingredients, (b) to prioritize e-liquid ingredients by calculating the e-tox index, and (c) to estimate acute toxicity of e-liquid mixtures QSAR models were generated using QSARINS software to fill the acute toxicity data gap of 264 e-liquid ingredients. As a second step, the potential acute toxicity of e-liquids mixtures was evaluated. Our preliminary data suggest that a computational approa serve as a roadmap to enable regulatory bodies to better regulate e-liquid composition and to contribute to consumer health protection.

Fu, Niankai published the artcileElectrocatalytic Radical Dichlorination of Alkenes with Nucleophilic Chlorine Sources, Related Products of esters-buliding-blocks, the publication is Journal of the American Chemical Society (2017), 139(43), 15548-15553, database is CAplus and MEDLINE.

We report a Mn-catalyzed electrochem. dichlorination of alkenes with MgCl₂ as the chlorine source. This method provides operationally simple, sustainable, and efficient access to a variety of vicinally dichlorinated compounds In particular, alkenes with oxidatively labile functional groups, such as alcs., aldehydes, sulfides, and amines, were transformed into the desired vicinal dichlorides with high chemoselectivity. Mechanistic data are consistent with metal-mediated Cl atom transfer as the predominant pathway enabling dual C-Cl bond formation and contradict an alternative pathway involving electrochem. evolution of chlorine gas followed by Cl₂-mediated electrophilic dichlorination.

A mild, metal-free, atm. oxygen-mediated radical hydrothiolation of alkenes (and alkyne) was reported. A variety of sulfur containing motifs including alkanethiols, thiophenols and thioacids undergo an atm. oxygen-mediated radical hydrothiolation reaction with a plethora of alkenes in good yield with excellent functional group compatibility, typically with short reaction times to furnished a range of functionalized products. Biomols. proved tolerant to the conditions and the procedure was robust and easily executable requiring no specialized equipment. Concise mechanistic studies confirmed that the process proceeded through radical intermediates in a thiol-ene reaction manifold. The methodol. offered an efficient “green” approach for thiol-ene mediated “click” ligation and a milder alternative to thermally initiated hydrothiolation processes.

Dong, Xichang published the artcileMerging shuttle reactions and paired electrolysis for reversible vicinal dihalogenations, Synthetic Route of 5205-11-8, the publication is Science (Washington, DC, United States) (2021), 371(6528), 507-514, database is CAplus and MEDLINE.

Vicinal dibromides and dichlorides are important commodity chems. and indispensable synthetic intermediates in modern chem. that are traditionally synthesized using hazardous elemental chlorine and bromine. Meanwhile, the environmental persistence of halogenated pollutants necessitates improved approaches to accelerate their remediation. Here, we introduce an electrochem. assisted shuttle (e-shuttle) paradigm for the facile and scalable interconversion of alkenes and vicinal dihalides, a class of reactions that can be used both to synthesize useful dihalogenated mols. from simple alkenes and to recycle waste material through retro-dihalogenation. The reaction is demonstrated using 1,2-dibromoethane, as well as 1,1,1,2-tetrachloroethane or 1,2-dichloroethane, to dibrominate or dichlorinate, resp., a wide range of alkenes in a simple setup with inexpensive graphite electrodes. Conversely, the hexachlorinated persistent pollutant lindane could be fully dechlorinated to benzene in soil samples using simple alkene acceptors.

Benini, Celine published the artcileVariations in the essential oils from ylang-ylang (Cananga odorata [Lam.] Hook f. & Thomson forma genuina) in the Western Indian Ocean islands, Product Details of C12H14O2, the publication is Flavour and Fragrance Journal (2012), 27(5), 356-366, database is CAplus.

Ylang-ylang essential oil is an important raw material for the fragrance industry. Despite its economic importance, to the best of our knowledge, no study has yet been undertaken to assess the chem. polymorphism of the different production areas. This underestimated variability is an interesting source of raw material for perfumers. That is why the variation in the chem. composition of four fractions of the essential oils extracted from Cananga odorata, grown in four locations Grande Comore, Mayotte, Nossi Be and Ambanja, was studied. A total of 119 compounds, representing 85.7-96.4% of the total essential oil composition, were identified using gas chromatog.-mass spectrometry and quantified by gas chromatog. with a flame ionization detector. Thirty-two compounds previously unreported in ylang-ylang essential oil were identified. The distinction between the Comoros and Madagascar groups was made on the basis of the chem. classes. It was possible to significantly distinguish the Grande Comore and Mayotte essential oil samples, as well as the Ambanja and Nossi Be essential oil samples, on the basis of their main compounds The aromatic compounds profile for the origin of each essential oil fraction was established. Regression trees were built, allowing the provenance of the essential oils prepared at the laboratory level to be easily differentiated on the basis of a limited number of major compounds Copyright © 2012 John Wiley & Sons, Ltd.

After fractionation by normal distillation under reduced pressure followed by silica gel chromatog., the volatile fractions of the hexane concrete of G. taitensis DC were investigated using GC/MS and GC/FTIR, and more than 150 components were identified. The major oxygenated constituents were linalool (4.4%), Me salicylate (2.5%), (Z)-3-hexenyl benzoate (2.2%), dihydroconiferyl alc. (1.1%), (Z)-3-hexenyl salicylate (0.7%), benzyl benzoate (6.2%), dihydroconiferyl acetate (12.2%), 2-phenylethyl benzoate (6.2%), benzyl salicylate (2.5%), geranyl benzoate (2.1%) and 2-phenylethyl salicylate (2.2%). The identification of numerous dihydroconiferyl esters appears to be unique to this species.

Steenhuisen, S.-L. published the artcileFloral scent in bird- and beetle-pollinated Protea species (Proteaceae): Chemistry, emission rates and function, Computed Properties of 5205-11-8, the publication is Phytochemistry (Elsevier) (2012), 78-87, database is CAplus and MEDLINE.

Evolutionary shifts between pollination systems are often accompanied by modifications of floral traits, including olfactory cues. The authors investigated the implications of a shift from passerine bird to beetle pollination in Protea for floral scent chem., and also explored the functional significance of Protea scent for pollinator attraction. Using headspace sampling and gas chromatog.-mass spectrometry, they found distinct differences in the emission rates and chem. composition of floral scents between eight bird- and four beetle-pollinated species. The amount of scent emitted from inflorescences of beetle-pollinated species was, on average, about 10-fold greater than that of bird-pollinated species. Floral scent of bird-pollinated species consists mainly of small amounts of green-leaf volatiles and benzenoid compounds, including benzaldehyde, anisole and benzyl alc. The floral scent of beetle-pollinated species is dominated by emissions of linalool, a wide variety of other monoterpenes and the benzenoid Me benzoate, which imparts a fruity odor to the human nose. The number of compounds recorded in the scent of beetle-pollinated species was, on average, greater than in bird-pollinated species (45 vs. 29 compounds, resp.). Choice experiments using a Y-maze showed that a primary pollinator of Protea species, the cetoniine beetle Atrichelaphinis tigrina, strongly preferred the scent of inflorescences of the beetle-pollinated Protea simplex over those of the bird-pollinated sympatric congener, Protea roupelliae. This study shows that a shift from passerine bird to insect pollination can be associated with marked up-regulation and compositional changes in floral scent emissions.

Keshavarz, Mohammad Hossein published the artcileSimple and reliable prediction of toxicological activities of benzoic acid derivatives without using any experimental data or computer codes, Application In Synthesis of 5205-11-8, the publication is Medicinal Chemistry Research (2013), 22(3), 1238-1257, database is CAplus.

Most of the benzoic acid derivatives can exhibit toxicity through serious public health and environmental problems. A reliable correlation is introduced for desk calculation of benzoic acid derivatives in rats via oral 50 % LD (LD₅₀). It can be easily used for any benzoic acid compound containing the carbon, hydrogen, nitrogen, oxygen and halogen atoms, or their sodium salts. The novel correlation is based on nitrogens, oxygens, and halogens as well as two correcting functions for increasing and decreasing toxicity of benzoic derivatives, which arise from some specific structural moieties. The predicted results for the toxicity of 81 benzoic acid derivatives in rats via oral LD₅₀ are more reliable than reported values by training and test sets of quant. structure-toxicity relationship (QSTR). The forecasting ability of the new model has also been checked for further 134 benzoic acid derivatives containing complex mol. structures.
