Studies on fused 2(1H)-pyridenethiones: New routes for the synthesis of fused 1H-pyrazolo[3,4-b]pyridines and fused thieno[2,3-b]pyridines

Article abstract of DOI:10.1246/bcsj.65.2241

A synthesis of fused 1H-pyrazolo[3,4-b]pyridines and fused thieno[2,3-b]pyridines utilizing fused 2(1H)-pyridinethiones as starting components is described. The structures of the products were assigned and confirmed on the basis of their elemental analysi
