Several new 4H-thiopyrans were synthesized via a facile one-step method. Structures and reaction mechanisms are also reported and supported by another synthetic routes.

Treatment of 2‐bromoacetylbenzofuran (2) with pyridine afforded its corresponding pyridinium bromide 3. The latter salt reacted with some activated alkenes and acetylenes to give the corresponding indolizinederivatives. Treatment of the salt 3 with benzylidenemalononitriles 9 afforded polysubstituted aniline derivatives, however with arylidenecyanothioacetamides 15 it gave the corresponding 4,5‐dihydrothiophenes
