α-ketoacid could be converted into a reactive acylating agent by treatment with hypervalentiodine(III) species, and in so doing, we discovered a novel decarboxylative acylation of alcohols that affords a variety of esters in excellent yields. The esterification has been applied to a sterol bearing a free carboxylicacid and shows unique chemoselectivity. The procedure is racemization-free and operates
