Abstract

Abstract A simple and highly efficient method for the preparation of tetrasubstituted furans starting from readily accessible propargylic alcohols and commercially available 1, 3- dicarbonyl compounds has been developed. The process, which proceeds in a one-pot manner, involves the initial propargylation of the 1, 3-dicarbonyl compound promoted by trifluoroacetic acid, and subsequent cycloisomerization of the resulting γ-ketoalkyne ...
