Indium(III) trifluoromethanesulfonate as an efficient catalyst for the deprotection of acetals and ketals.

Brian T Gregg1, Kathryn C Golden, John F Quinn.   

Abstract

Acetals and ketals are readily deprotected under neutral conditions in the presence of acetone and catalytic amounts of indium(III) trifluoromethanesulfonate (<0.8 mol %) at room temperature or mild microwave heating conditions to give the corresponding aldehydes and ketones in good to excellent yields.
