A Novel Way to Tricyclic Heteroaromatics; Thiazolo[5,4-b]thieno[3,2-e]pyridine Derivatives

Abstract Thiazolo[5,4- b ]thieno[3,2- e ]pyridine derivatives, novel tricyclic heteroaromatics, have been designed and synthesized by a one-pot reaction of diazepinethiones and aldehydes. This reaction is based on a novel rearrangement reaction of seven-membered 1,4-diazepine-2-thiones to six-member...

Zusammenfassung:Abstract Thiazolo[5,4- b ]thieno[3,2- e ]pyridine derivatives, novel tricyclic heteroaromatics, have been designed and synthesized by a one-pot reaction of diazepinethiones and aldehydes. This reaction is based on a novel rearrangement reaction of seven-membered 1,4-diazepine-2-thiones to six-membered 3-aminopyridine-2-thiols catalyzed by scandium(III) triflate.
