Studies with polyfunctionally substituted heteroaromatics, a new route to synthesis of thiopyrano[3,2-c]pyridine, thiopyrano[4,3-b]pyridine, and bipyridyl derivatives

Article abstract of DOI:10.1080/10426509708033707

Pyridine derivatives (4a, d, e) were reacted with carbon disulfide in dry tetrahydrofurane (THF) in the presence of potassium tert-butoxide under Argon to yield thiopyanopyridine derivatives (7, 10). Also (2a, 4c) were reacted with carbon disullide under the same condition producing the dithioacetal derivatives (13) which were converted to bipyridyl derivatives (14) via reaction with cyanothioacetamide in isopropyl alcohol and sodium isopropoxide.
