An efficient oxytrifluoromethylation of allyl alcohols has been developed using Togni’s reagent II as a trifluoromethylation reagent and cuprous 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 α-CF3-substituted epoxides.
