Wood, Murray R. published the artcileSelective one-pot synthesis of trithiocarbonates, xanthates, and dithiocarbamates for use in RAFT/MADIX living radical polymerizations, Application of Ethyl 2-mercaptopropanoate, the publication is Organic Letters (2006), 8(4), 553-556, database is CAplus and MEDLINE.

A facile route is developed for the production of chain transfer agents for reversible addition fragmentation chain transfer (RAFT) and macromol. design via the interchange of xanthates (MADIX) polymerizations, via a one-pot reaction. 1,1′-Thiocarbonyl diimidazole (TCDI) undergoes controlled monosubstitution when reacted with secondary thiols or alcs. The intermediate S/O-esters of imidazole-N-thionocarboxylic acid react efficiently with a range of primary thiols, alcs., and amines to form asym. dithiocarbonates, trithiocarbonates, and dithiocarbamates, resp. The synthesis provides a facile approach to the controlled radical polymerization of vinyl monomers through the reversible addition-fragmentation chain transfer (RAFT) mechanism.

Wood, Murray R. published the artcileInvestigation of the Experimental Factors Affecting the Trithiocarbonate-Mediated RAFT Polymerization of Methyl Acrylate, Safety of Ethyl 2-mercaptopropanoate, the publication is Australian Journal of Chemistry (2007), 60(10), 772-778, database is CAplus.

The reversible addition-fragmentation chain transfer polymerization of acrylates, using Me acrylate (MA) as a monomer model, mediated by a trithiocarbonate was tested under several conditions where the exptl. parameters were systematically altered. The most significant parameter in controlling the rate and control of the polymerization was found to be the ratio of chain transfer agent (CTA) to initiator. Decreasing this ratio increased the rate of polymerization and had little noticeable effect on the control over mol. weight distribution. A ratio of CTA to initiator of unity was shown to give the best compromise between rate and control of the polymerization Targeted d.p. (equivalent to ratios of monomer to CTA) had negligible effect on the rate of polymerization and polydispersity index (PDI). Performing the polymerization in the presence of solvent (up to 41.2% (weight/weight) in toluene) had no neg. effect on the rate of polymerization Indeed, marginally higher conversions and lower PDIs than for bulk polymerization were achieved for similar reaction times. A higher amount of toluene (66.6% (weight/weight)) induced a lower rate of polymerization, but the evolution of mol. weight and PDI were unaffected. Polymerizations performed in the presence of toluene, N,N-dimethylformamide, and Me Et ketone showed that solvent polarity and aromaticity had no observable effect on the rate of polymerization and over the control of mol. weight distribution. The optimum conditions for the polymerization of MA, mediated by 2-ethylthiocarbonylsulfanyl-propionic acid Et ester at 50°C were found to be [CTA]/[AIBN] = 1/1 and ∼ 40% solvent (weight/weight).

Rasgele, Pinar Goc published the artcileChemical Compositions and Antimutagenic Effects of Ethanolic Extracts of Stachys thirkei and Stachys Annua subsp. Annua Using the Ames Assay, COA of Formula: C5H10O2S, the publication is Pharmaceutical Chemistry Journal (2021), 54(12), 1255-1262, database is CAplus.

In this study, antimutagenic effects of ethanolic extracts of Stachys thirkei and Stachys annua subsp. annua belonging to Lamiaceae family that grow in Duzce of Turkey were investigated on Salmonella typhimurium TA98 and TA100 strains without metabolic activation using Salmonella/microsome test system. Three different concentrations (0.025, 0.05 and 0.1 mg/plate) of the ethanolic extracts of S. thirkei and S. annua subsp. were used as active materials in which the major components were 2-ethylhexanol (30.012%) and 2-beta-pinene (26.40%), resp. The highest concentration (0.1 mg/plate) of S. thirkei had a moderate antimutagenic effect on the Salmonella typhimurium TA98 strain with a 26.79% inhibition rate. It was also established that the extract of S. thirkei at highest concentration (0.1 mg/plate) exhibited strong antimutagenic effect (with 44.03% maximum inhibition) on TA100 strain. Furthermore, it was found that 0.05 mg/plate ethanolic extract showed moderate antimutagenic activity with 25.55% inhibition rate. The highest concentration (0.1 mg/plate) of ethanolic extract of S. annua subsp. showed moderate antimutagenic activity on both Salmonella typhimurium TA98 and TA100 strains with inhibition rates of 20.39 and 22.13%, resp. No antimutagenic activity on Salmonella typhimurium TA98 and TA100 strains was observed at the lowest doses of both plant species. As a result, it is concluded that S. thirkei and annua subsp. have antimutagenic activity and further studies may be recommended in terms of different parameters.

A visible light-promoted hydrosilylation of alkynes was explored and achieved using 1 mol % organic dye Eosin Y as the photocatalyst and a catalytic amount of thiol as the radical quencher. The corresponding alkenylsilanes were provided with high regio- and stereoselectivites in the reactions of various terminal and internal alkynes. The reaction is preferentially initiated by a single electron transfer process, and a photoredox pathway is suggested.

Wang, Da-Wei published the artcileDiscovery of N-Phenylaminomethylthioacetylpyrimidine-2,4-diones as Protoporphyrinogen IX Oxidase Inhibitors through a Reaction Intermediate Derivation Approach, Recommanded Product: Ethyl 2-mercaptopropanoate, the publication is Journal of Agricultural and Food Chemistry (2021), 69(14), 4081-4092, database is CAplus and MEDLINE.

Protoporphyrinogen oxidase (PPO, EC 1.3.3.4) is an effective target for green herbicide discovery. In this work, we reported the unexpected discovery of a novel series of N-phenylaminomethylthioacetylpyrimidine-2,4-diones (2-6) as promising PPO inhibitors based on investigating the reaction intermediates of our initially designed N-phenyluracil thiazolidinone (1). An efficient one-pot procedure that gave 41 target compounds in good to high yields was developed. Systematic Nicotiana tabacum PPO (NtPPO) inhibitory and herbicidal activity evaluations led to identifying some compounds with improved NtPPO inhibition potency than saflufenacil and good post-emergence herbicidal activity at 37.5-150 g of ai/ha. Among these analogs, Et 2-((((2-chloro-4-fluoro-5-(3-methyl-2,6-dioxo-4-(trifluoromethyl)-3,6-dihydropyrimidin-1(2H)-yl)phenyl)amino)methyl)thio)acetate (2c) (K_i = 11 nM), exhibited excellent weed control at 37.5-150 g of ai/ha and was safe for rice at 150 g of ai/ha, indicating that compound 2c has the potential to be developed as a new herbicide for weed management in paddy fields. Addnl., our mol. simulation and metabolism studies showed that the side chains of compound 2c could form a hydrogen-bond-mediated seven-membered ring system; substituting a Me group at R¹ could reinforce the hydrogen bond of the ring system and reduce the metabolic rate of target compounds in planta.

Deuteration is a widely used labeling technique. Through a visible-light induced desulfurization and radical addition process in EtOAc-D₂O, the authors were able to develop the direct synthesis of γ-deuterated carbonyl compounds from α-sulfide ketones and alkenes. Products with different functionalities were efficiently synthesized with high deuteration. This mild and metal-free method provides a valuable tool for medicinal and synthetic chemists.
