Preparation of N-Boc N-Alkyl Glycines for Peptoid Synthesis

Abstract
A series of N-tert-butoxycarbonylated N-allyl, N-propargyl, N-benzyl or branched N-alkyl glycines, useful building blocks for the synthesis of N-alkyl glycine oligomers, have been prepared by N-alkylation of N-Boc glycine or by a two-step method: reductive alkylation and tert-butoxycarbonylation.
