We have developed an efficient and simple method for direct transformation of acetals to carboxylicacid esters. The method consists of treatment of acetals with carboxylic anhydrides in the presence of borontrifluoride etherate as a catalyst and affords the corresponding ester derivatives in high yields with retention of configuration in the alcohol moiety. Some mechanistic aspects of this synthetically
