3,3-tetrasubstituted 2,3-epoxyalcohols with several kinds of protecting groups was investigated. When SnCl4 is used as a Lewis acid, the reaction proceeds in a regio- and stereo-controlled manner to afford two types of carbonyl compounds selectively from a single 2,3-epoxyalcohol only by changing the protecting group of the alcohol. The method was then applied to the formation of two types of acyclic
