Abstract

A highly selective cleavage of the t-butoxycarbonyl group has been achieved in high yields using CeCl3·7H2O-NaI in acetonitrile at ambient temperature under neutral conditions. This method is mild and compatible with a wide range of functional groups such as THP, TBDMS, TBDPS, trityl ethers, mono-BOC or Cbz protected amines, acetamide, sulfonamide and benzamide etc., present in the substrate.
