摘要

A one-pot tandem aldol/desilylation/CuAAC sequence is developed, allowing the facile synthesis of tertiary alcohols featuring an α-difluoroketone moiety and a 1,2,3-triazole at the α position in moderate to good yields, with an operationally friendly manner. While Bi(OTf) ₃was the optimal catalyst for the Mukaiyama-aldol reaction of silyl-α-ketoalkynes and difluoroenoxysilanes, CuCl was found to efficiently mediate the alkyne-azide cycloaddition.
