New thieno[2,3-b]pyridine-fused [1,2,4]triazolo[4,3-a]pyrimidinones were obtained by the [5+1] heterocyclization of the appropriate thieno[2,3-b]pyridines followed by the Smiles-type reaction protocol. In general, the triazoles tested exhibited bette
A novel series of thieno[2,3-b]pyridines was prepared via an one-step protocol in excellent yields. The protocol involved the reaction of pyridine-2(1H)-thiones with the appropriate halogen containing reagents in ethanolic sodium ethoxide solution un
