N,O‐bisFmoc derivatives of N‐(2‐hydroxy‐4‐methoxybenzyl)‐amino acids: Useful intermediates in peptide synthesis

Abstract
2‐Hydroxy‐4‐methoxybenzyl‐amino acid residues inhibit interchain association in solid phase peptide synthesis. They are easily introduced through their N,O‐bisFmoc derivatives. Preparation of a range of these derivatives is described.
