Fused thieno[2,3-b]pyridines: Synthesis and characterization of new condensed pyridothienopyrimidines

Reaction of cyanopyridine-2(1H)-thiones 2a,b with chloroacetonitrile gave the corresponding 3-aminothieno[2,3-b]pyridine-2-carbonitriles 4a,b. Condensation of 4a,b with triethyl orthoformate produced the methanimidate derivatives 6a,b which upon treatment

Pyridine-2(1H)-thione in heterocyclic synthesis: Synthesis of some new nicotinic acid ester, thieno[2,3-b]pyridine, pyrido[3′,2′:4,5]thieno [3,2-d]pyrimidine, and Thiazolylpyrazolo-[3,4-b]pyridine derivatives

Nicotinic acid esters 3a-c were prepared by the reaction of pyridine-2(1H)-thione derivative 1 with a-halo-reagents 2a-c. Compounds 3a-c underwent cyclization to the corresponding thieno[2,3-b]pyridines 4a-c via boiling in ethanol/piperidine solution. Com
