This paper details an efficient method for a one-step transformation of the trityl ether to the acetonide. Treatment of trityl ether with a mixture of trifluoroacetic acid, 2,2-dimethoxy propane and camphorsulfonic acid as catalyst in dichloromethane through detritylation followed by acetonization gave the acetonide in high yield. This method was highly applicable to use with detritylation of the alcohols bearing acid-hydrolyzable functionalities.

Key words: trityl ether, acetonide, detritylation
