An efficient approach to the parallel synthesis of benzimidazoles from anilines is described. Library approaches to vary the N1 and C2 vectors of benzimidazoles are well established; however, C4-C7 variation has traditionally relied on 1,2-dianiline build

An N-heterocyclic carbene-catalyzed annulation of ynals and amidines has been reported to construct pyrimidin-4-ones. The protocol features a broad substrate scope and mild conditions. Furthermore, an oxidative strategy to catalytically generate ynal-deri

A number of ethyl 3-substituted-phenyl-2-methylmercapto/ phenyl/ methyl-4(3H)-pyrimidone-5-carboxylates (V) have been prepared by the reaction of amidines (III) with diethyl ethoxymethylenemalonate.In order to confirm the structure (V), ethyl 3-(2'-methylphenyl)-2-methylmercapto-4(3H)pyrimidone-5-carboxylate (103) has been transformed into the earlier synthesised 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone (115) by decarboxylation of 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone-5-carboxylic acid (114), obtained by the alkaline hydrolysis of 103.Someof these compounds have shown antiinflammatory, diuretic and antipassive cutaneous anaphylaxis activities.
