A highly selective hydrolysis of the 1,3-oxathio- and 1,3-dithioacetals has been achieved in high yields using CeCl3.7H(2)O-NaI in acetonitrile at reflux temperature under neutral conditions. This method is mild and compatible with a wide range of functional groups such as TBDPS. THP, PMB, MOM, allyl, propargyl. prenyl, benzyl ethers. carbamates and acetate, etc., present in the substrate. (C) 2002 Elsevier Science Ltd. All rights reserved.
