Pibiri, Ivana published the artcilePhotochemical functionalization of allyl benzoates by C-H insertion, SDS of cas: 5205-11-8, the publication is Tetrahedron (2013), 69(30), 6065-6069, database is CAplus.

The photoreactivity of allyl benzoates, containing an electron-rich double bond, has been explored by irradiation at 305 nm in different solvents. Solvent addition products arising from an insertion of the alpha H-C bonds of THF, dioxane, and i-PrOH to the allylic double bond was realized. The observed reactivity depended on reaction conditions and substitution pattern of the substrate. A DFT study on this unusual reaction was performed allowing the formulation of two mechanistic pathways.

Kus, Piotr M. published the artcileDevelopment of supercritical CO₂ extraction of bioactive phytochemicals from black poplar (Populus nigra L.) buds followed by GC-MS and UHPLC-DAD-QqTOF-MS, Related Products of esters-buliding-blocks, the publication is Journal of Pharmaceutical and Biomedical Analysis (2018), 15-27, database is CAplus and MEDLINE.

The supercritical CO₂ (SC-CO₂) extraction process of black poplar (Populus nigra L.) buds was optimized (pressure, temperature) based on the yields of major phytochems. (volatiles and non-volatiles). The optimal settings were 30 MPa/60°C. Major volatiles determined by GC-MS in the optimized SC-CO₂ extract (mg of benzyl salicylate equivalent (BSE) per 100 g of buds) were: pinostrobin chalcone (1574.2), β-eudesmol (640.8), α-eudesmol (581.9), 2-methyl-2-butenyl-p-coumarate (289.9), pentyl-p-coumarate (457.0), γ-eudesmol (294.4), and benzyl salicylate (289.2). Partial qual. similarity was observed between SC-CO₂ extracts and corresponding hydrodistd. essential oil dominated by sesquiterpenes, but with lower yields. Major compounds (mg per 100 g of buds) identified by UHPLC-DAD-QqTOF-MS in the optimized SC-CO₂ extract were: pinostrobin (751.7), pinocembrin (485.6), 3-O-pinobanksin acetate and methyl-butenyl-p-coumarate (290.2; 144.9 of pinobanksin and p-coumaric acid equivalent, resp.). SC-CO₂ extraction was found useful for green, efficient and simultaneous extraction of both volatile/non-volatile, bioactive phytochems. of poplar buds – precursors of poplar-type propolis.

Shigehisa, Hiroki published the artcileCobalt-Catalyzed Hydrofluorination of Unactivated Olefins: A Radical Approach of Fluorine Transfer, Recommanded Product: 3-Methylbut-2-en-1-yl benzoate, the publication is Organic Letters (2013), 15(20), 5158-5161, database is CAplus and MEDLINE.

Alkyl fluorides were prepared regioselectively in 41-82% yields by hydrofluorination of alkenes with 1-fluoro-2,4,6-trimethylpyridinium tetrafluoroborate and 1,1,3,3-tetramethyldisiloxane in the presence of a cobalt salen complex; the reactions occurred to give the Markovnikov regioisomers exclusively, tolerated acetal, ester, amide, tosylate, nitro, bromo, and thienyl moieties, and were performed (in three cases) on approx. 1 g scale in similar yields to those found on smaller scale. Reaction of a diallylsulfonamide yielded a fluoroalkylpyrrolidine, implying the generation of a radical intermediate in the hydrofluorination reaction.

Tanaka, Shinji published the artcileEpoxide as precatalyst for metal-free catalytic transesterification, Related Products of esters-buliding-blocks, the publication is Tetrahedron Letters (2019), 60(30), 2009-2013, database is CAplus.

Transesterification of Me-esters was accelerated by an in situ-generated metal-free catalyst comprising a quaternary alkylammonium salt and an epoxide was developed. The combination of a quaternary alkylammonium acetate and glycidol was optimal, and various esters R¹CO₂R² [R¹ = 2-thiophenyl, Ph, Bn, etc.; R² = 2-Bu, n-C₆H₁₃, Bn, prenyl] were synthesized from Me-esters with alcs. in good to excellent yield. Anal. of the catalyst solution revealed that basic species were generated by the ring-opening reaction of epoxide.

Bian, Kang-Jie published the artcileModular Difunctionalization of Unactivated Alkenes through Bio-Inspired Radical Ligand Transfer Catalysis, Recommanded Product: 3-Methylbut-2-en-1-yl benzoate, the publication is Journal of the American Chemical Society (2022), 144(26), 11810-11821, database is CAplus and MEDLINE.

Herein, the first modular, dual catalytic difunctionalization of unactivated alkenes viz., but-3-en-1-ylbenzene, 3-methylbut-2-en-1-yl benzoate, pent-4-en-1-yl 2-[4-[(2-oxocyclopentyl)methyl]phenyl]propanoate, etc. via manganese-catalyzed radical ligand transfer (RLT) was reported. This RLT elementary step involves a coordinated nucleophile rebounding to a carbon-centered radical to form a new C-X bond in analogy to the radical rebound step in metalloenzymes. The protocol leverages the synergetic cooperation of both a photocatalyst and earth-abundant manganese complex to deliver two radical species in succession to minimally functionalized alkenes, enabling modular diversification of the radical intermediate by a high-valent manganese species capable of delivering various external nucleophiles. A broad scope (97 examples, including drugs/natural product motifs), mild conditions, and excellent chemoselectivity were shown for a variety of substrates and fluoroalkyl fragments. Mechanistic and kinetic studies provide insights into the radical nature of the dual catalytic transformation and support radical ligand transfer (RLT) as a new strategy to deliver diverse functionality selectively to carbon-centered radicals.

Mahajani, Nivedita S. published the artcileEster Formation via Symbiotic Activation Utilizing Trichloroacetimidate Electrophiles, Formula: C12H14O2, the publication is Journal of Organic Chemistry (2019), 84(12), 7871-7882, database is CAplus and MEDLINE.

Trichloroacetimidates are useful reagents for the synthesis of esters under mild conditions that do not require an exogenous promoter. These conditions avoid the undesired decomposition of substrates with sensitive functional groups that are often observed with the use of strong Lewis or Bronsted acids. With heating, these reactions have been extended to benzyl esters without electron-donating groups. These inexpensive and convenient methods should find application in the formation of esters in complex substrates.

Rolli, Enrico published the artcilePhytotoxic Effects and Phytochemical Fingerprinting of Hydrodistilled Oil, Enriched Fractions, and Isolated Compounds Obtained from Cryptocarya massoy (Oken) Kosterm. Bark, Recommanded Product: 3-Methylbut-2-en-1-yl benzoate, the publication is Chemistry & Biodiversity (2016), 13(1), 66-76, database is CAplus and MEDLINE.

The hydrodistd. oil of Cryptocarya massoy bark was characterized by GC-FID and GC/MS analyses, allowing the identification of unusual C₁₀ massoia lactone (3, 56.2%), C₁₂ massoia lactone (4, 16.5%), benzyl benzoate (1, 12.7%), C₈ massoia lactone (3.4%), δ-decalactone (5, 1.5%), and benzyl salicylate (2, 1.8%) as main constituents. The phytotoxic activities of the oil, three enriched fractions (lactone-rich, ester-rich, and sesquiterpene-rich), and four constituents (compounds 1, 2, 5, and δ-dodecalactone (6)) against Lycopersicon esculentum and Cucumis sativus seeds and seedlings were screened. At a concentration of 1000 μl/l, the essential oil and the massoia lactone-rich fraction caused a complete inhibition of the germination of both seeds, and, when applied on tomato plantlets, they induced an 85 and 100% dieback, resp. These performances exceeded those of the well-known phytotoxic essential oils of Syzygium aromaticum and Cymbopogon citratus, already used in com. products for the weed and pest management. The same substances were also evaluated against four phytopathogenic bacteria and ten phytopathogenic fungi, providing EC₅₀ values against the most susceptible strains in the 100-500 μl/l range for the essential oil and in the 10-50 μl/l range for compound 6 and the lactone-rich fraction. The phytotoxic behavior was related mainly to massoia lactones and benzyl esters, while a greater amount of 6 may infer a good activity against some phytopathogenic fungi. Further investigations of these secondary metabolites are warranted, to evaluate their use as natural herbicides.
