Abstract:

AbstractThiazolidine-2-thiones were prepared via a novel multicomponent reaction of primary amines (amino acids), carbon disulfide, and γ-bromocrotonates. The reaction proceeds via a domino alkylation/intramolecular Michael addition to provide the corresponding thiazolidine-2-thiones in high to excellent yields. By using diamines in this protocol, bis(thiazolidine-2-thiones) derivatives were synthesized. The synthetic utility of the adducts was demonstrated by hydrolysis, amidation, and oxidation reactions.

The Cu(OTf)2-catalysed expeditious synthesis of 1,3-oxazin-2-ones(thiones) from unprotected D-glucose and D-xylose in excellent yields is reported. Cu(OTf)2 plays a dual role of a Lewis acid and an oxidant for dehydrazination, which is the cornerstone in the present investigation. The 1,3-oxazin-2-ones(thiones) serve as synthons for diversity oriented synthesis of structurally distinct bicyclic 1,3-oxazin-2-ones(thiones), when subjected to Malaprade reaction, followed by Cu(OTf)2-catalysed cyclisation with an appropriate traditional reagent such as phenylhydrazine, amidines, hydroxylamine, or

An efficient method for carbon–carbon bond formation is described. The process employs the palladium-catalyzed and copper-mediated cross-coupling of quinoline-2-(1H)-thiones with arylboronic acids or alkynes through C–S bond cleavage without an inert atmosphere. The method provides rapid and general access to a diverse range of 2-substituted quinolines in a single step from a wide range of quinoline-2-(1H)-thiones and arylboronic acids or alkynes.

Department of Chemistry, University of Kerala, Trivandrum-695 034 <em>Manuscript received 3 July 1990. revised 4 January 1991, accepted 4 December 1991</em> Condensation of a few 2-amino-3-cyano-4,5-disubstituted-furan with isotbiocyanates in the presence of a base has been found to result in the formation or 3-alkyl/aryl-4-imino-5. 6-disubstituted-furo[2, 3-<em>d</em>]pyrimidine-2-thiones (3a- n). These compounds on refluxing with aqueous dimetbylformamide was found to rearrange and form 4-arylaminofuro[1,3-<em>d</em>)pyridine-2-thiones.

Abstract:

Reaction of 8-bromoadenine derivatives 1 with thiourea in ethanol or butanol was used for the synthesis of the corresponding N9-substituted 6-amino-7H-purine-8(9H)-thiones 2. 8-(Methylsulfanyl)adenine derivatives 3 were prepared by reaction of thiones 2 with iodomethane in 1 M sodium methoxide or in aqueous 1.5 M potassium hydroxide. Alkylation of 6-amino-7H-purine-8(9H)-thione (2a) proceeds preferentially on the sulfur atom. Under similar conditions, alkylation of 8-(methylsulfanyl)adenine (3a) with diverse alkylation agents afforded N9-substituted adenine derivatives 3 and 6, and N3-substitu

Abstract:

Introduction. This article presents an analysis of the antioxidant activity of 4-amino-5-(2-, 3-, 4-nitrophenyl)-1H-1,2,4-triazole-3-thiones and their synthetic analogues, 5-(4-methoxyphenyl, 3,4,5-trimethoxyphenyl)-1,2,4-triazole-3-thiones and their synthetic analogues, and 5-(quinolin-2-yl, 2-hydroxyquinolin-4-yl)-4-R1-1,2,4-triazole-3-thiones. The main conclusions drawn from these studies are as follows: The purpose: to evaluate the antioxidant activity of 1,2,4-triazole derivatives, specifically 4-amino-5-(2-, 3-, 4-nitrophenyl)-1H-1,2,4-triazole-3-thiones, 5-(4-methoxyphenyl-, 3,4,5-trime
