Amberlyst 15 is an efficient catalyst for the reaction of aryl-substituted oxiranes with acetone to prepare 2,2-dimethyl- 1,3-dioxolanes in high yields. trans-2,3-Diaryloxiranes afford trans-acetonides enantiospecifically at room temperature, and the use of enantiopure 2,3-diaryloxiranes results in no loss of stereochemical integrity in the resulting trans-acetonides.
