- Preparation and synthetic utility of 3-(benzotriazol-1-ylmethyl)areno- and -hetareno[b]thiophenes
-
The preparation and synthetic utility of 3-(benzotriazol-1-ylmethyl)areno- and -hetareno[b]thiophenes were studied. It was prepared through the side chain elaboration of 3-(benzotriazol-1-ylmethyl)thiophenes. The compounds were characterized by nuclear ma

- A new three-carbon synthon for efficient synthesis of benzannelated and 1-(2-arylethenyl) heterocycles
-
The novel three-carbon synthon 1-(1H-1,2,3-benzotriazol-1-yl)-3-chloroacetone for the synthesis of benzothiazoles, pyrido[1,2-a]indoles, and styryl-substituted indolizines and imidazo[1,2-a]pyridines is reported. The proposed routes are a general and efficient approach for heterocyclizations followed by benzannelations or attachment of arylethenyl pharmacophores.
