Ye, Zenghui published the artcileEnantiospecific electrochemical rearrangement for the synthesis of hindered triazolopyridinone derivatives, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is functionalized hindered triazolopyridinone derivative enantioselective preparation; pyridyl hydrazide preparation electrochem oxidative rearrangement; carboxylic acid hydrazine pyridyl hydrazide preparation.

An electrochem. rearrangement for efficient synthesis of inaccessible triazolopyridinones I [R1 = H, Me, Ph, etc.; R2 = H, Me, F, etc., R3 = Et, OTBS, 2-thienyl, etc.; R1R2 = cyclpropyl, adamantan-1-yl, tetrahydrofuran-2-yl, etc.; R4 = H, 8-Cl, 6-COOEt, etc.] with diverse alkyl carboxylic acids as starting materials was reported. This enabled efficient preparation of more than 60 functionalized triazolopyridinones I under mild conditions in a sustainable manner. This method was evaluated for late stage modification of bioactive natural products, amino acids and pharmaceuticals, and it was further applied to decagram scale preparation of enantiopure triazolopyridinones. The control experiments supported a mechanism involving an oxidative cyclization and 1,2-carbon migration. This facile and scalable rearrangement demonstrated power of electrochem. synthesis to access otherwise-inaccessible triazolopyridinones and may find wide application in organic, material and medicinal chem.

Matsubara, Ryosuke published the artcileModular Synthesis of Carbon-Substituted Furoxans via Radical Addition Pathway. Useful Tool for Transformation of Aliphatic Carboxylic Acids Based on “”Build-and-Scrap”” Strategy, Application of 4-Methoxyphenylacetic acid, the main research area is furoxan regioselective preparation; silver catalyst oxidative radical substitution arylsulfonyl furoxan alkylcarboxylic acid; build and scrap strategy radical functionalization furoxan.

Bis(arylsulfonyl)furoxans such as I (R = 4-MeC6H4, 4-ClC6H4, 4-FC6H4, 3-F3CC6H4, Ph) underwent regioselective substitution reactions with alkyl radicals generated from carboxylic acids such as Ph(CH2)3CO2H with K2S2O8 in the presence of AgNO3 in aqueous MeCN, allowing regioselective functionalization of furoxans. Further isomerization and substitution reactions allowed the regioselective preparation of a variety of furoxans such as II (R1 = PhSO2, 4-MeC6H4SO2, Me(CH2)5CC, F3C, EtO, PhO, EtS). II (R = PhSO2, EtO, F3C) were converted to a variety of compounds including oximes, amines and diamines, nitro compounds, nitriles, an oxadiazole, and isoxazoles and dihydroisoxazoles; the furoxan moiety can thus be used to form a variety of functional groups by a “”build-and-scrap”” strategy. The mechanisms of the addition and elimination steps of the regioselective substitution reactions bis(arylsulfonyl)furoxans was studied to account for the observed regioselectivities.

Gunturi, S. B. published the artcilePrediction of skin sensitization potential using D-optimal design and GA-kNN classification methods, Safety of 5-Methyl-2-phenylhex-2-enal, the main research area is computational model skin sensitization D optimal design GA kNN.

Modeling of skin sensitization data of 255 diverse compounds and 450 calculated descriptors was performed to develop global predictive classification models that are applicable to whole chem. space. With this aim, we employed two automated procedures, (a) D-optimal design to select optimal members of the training and test sets and (b) k-Nearest Neighbor classification (kNN) method along with Genetic Algorithms (GA-kNN Classification) to select significant and independent descriptors in order to build the models. This methodol. helped us to derive multiple models, M1-M5, that are stable and robust. The best among them, model M1 (CCRtrain = 84.3%, CCRtest = 87.2% and CCRext = 80.4%), is based on six neighbors and nine descriptors and further suggests that: (a) it is stable and robust and performs better than the reported models in literature, and (b) the combination of D-optimal design and GA-kNN classification approach is a very promising approach. Consensus prediction based on the models M1-M5 improved the CCR of training, test and external validation datasets by 3.8%, 4.45% and 3.85%, resp., over M1. From the anal. of the phys. meaning of the selected descriptors, it is inferred that the skin sensitization potential of small organic compounds can be accurately predicted using calculated descriptors that code for the following fundamental properties: (i) lipophilicity, (ii) at. polarizability, (iii) shape, (iii) electrostatic interactions, and (iv) chem. reactivity.

Nguyen, Khang X. published the artcileSulfur-Mediated Decarboxylative Coupling of 2-Nitrobenzyl Alcohols and Arylacetic Acids, Safety of 4-Methoxyphenylacetic acid, the main research area is nitro benzylalc arylacetic acid sulfur mediated decarboxylative coupling; aryl quinazoline.

A new method for the synthesis of substituted quinazolines by the condensation of 2-nitrobenzyl alcs. with arylacetic acids. The transformation requires the use of urea as a nitrogen source, elemental sulfur as a promoter, DABCO as a base and DMSO as a solvent. Functionalities such as chloro, fluoro, trifluoromethyl, thienyl and indolyl groups were all compatible with the reaction conditions. Because this method uses stable simple substrates to obtain the N,N-heterocycles in the absence of transition metals, it offers a potential pathway for preparing complex structures under mild conditions.
