Abstract

A simple and efficient method for the selective removal of N-Boc group by employing tin(II) trifluoromethanesulfonate [Sn(OTf)2] in CH2Cl2 or solvent-free conditions was developed. The scope of this procedure is explored for the deprotection of a variety of amines, including amino acid derivatives.
