Abstract
An efficient oxytrifluoromethylation of 1-aryl-substituted allyl alcohols has been developed using Togni’s reagent II as a trifluoromethylation reagent and copper(I) chloride as a catalyst. This reaction proceeded through a one-pot process of trifluoromethylation followed by nucleophilic attack of the vicinal hydroxyl group. This strategy features good diastereoselectivity and broad substrate scope, which provides a facile access to various 2-aryl-3-(2,2,2-trifluoroethyl)oxiranes.
