Abstract:

A library of new spiro pyrido[3',2':4,5]thieno[3,2-d]pyrimidines was synthesized by reaction of 3-aminothieno[2,3-b]pyridine-2-carboxamides with ninhydrin hydrate. The optimal reaction conditions and mechanism are discussed.

Keywords: spiro compoinds, indane-1,2,3-trione, thieno[2,3-b]pyridines, pyrido[3',2':4,5]thieno[3,2-d]pyrimidines
