Abstract

ABSTRACT: A domino one‐pot synthesis of 2H‐chromenes and 4H‐chromenes starting from phenols and terminal acetylenes under solvent‐free and atom economy conditions, is described. This annulation reaction between phenols with alkynes, is promoted by simple Lewis acid ZnCl2. Significantly, to the best of our knowledge, the synthesis of 2H‐chromenes, is first of its kind, particularly, using terminal alkyl acetylenes. The present strategy shows a broad substrate scope and good functional group tolerance
