Epoxides dissolved in acetone can be converted almost quantitatively in acetonides in the presence of catalytic amounts of erhium(III) triflate. The procedure can be usefully applied to other substrates and can be extended to other ketones.
Conversion of Epoxides to 1,3-Dioxolanes Catalyzed by Tin(II) Chloride

Anhydrous tin(II) chloride is an efficient catalyst for the reaction of epoxides with acetone to prepare 2,2-dimethyl-1,3-dioxolanes (acetonides) in good to excellent yields. Mono-, di-, and trisubstituted epoxides participate equally well in this diastereospecific reaction. The use of single enantiomer epoxides under the reported conditions results in significant erosion of optical activity.
