Some reactions of 2-functionalized 3-amino-4-aryl-6-(2′-thienyl)-thieno[2,3-B]-pyridines: Synthesis of new pyridothienopyrimidines, pyridothienotriazines and related fused tetracyclic systems

4-Aryl-3-cyano-6-(2′-thienyl)-pyridine-2(1H)-thiones (2a-c) were prepared and reacted with chloroacetonitrile or chloroacetamide to furnish 3-amino-4-aryl-6-(2′-thienyl)-thieno[2,3-b]pyridine-2-carbonitriles (4a-c) and 2-carboxamide analogs 6a-c respectiv
