Abstract
AbstractAn effective redox‐neutral strategy to synthesize aryl/alkynyl and alkyl/alkynyl substituted 1‐naphthol derivatives has been efficaciously developed by Rh(III)‐catalyzed [4+2]‐annulation of sulfoxonium ylides and 1,3‐diynes with excellent regio‐ and chemoselectivity. Subsequently, the same strategy was extended to furnish various unsymmetrical binaphthol motifs in one‐pot manner. Interestingly, the TMS‐derived 1,3‐diyne predominantly delivered the 3‐alkynyl‐1‐naphthol via desilylation pathway. The salient features such as traceless directing group, broad substrate scope, good functional group tolerance, and operationally simple conditions made the present protocol more valuable and appealing.
