摘要

Abstract The amino and carboxy functions in N-Fmoc-α-amino acid and N-Fmoc-peptide methyl esters can be alternatively and chemoselectively deprotected by treatment with the reagent system AlCl 3/N, N-dimethylaniline (DMA). The chemoselectivity of the process is controlled by modulating the relative molar ratio of the Lewis acid and DMA.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
