N-Benzhydryl-glycolamide esters (OBg esters) of various N-protected amino acids have been synthesized. In order to demonstrate their usefulness in peptide chemistry, the syntheses of For-Met-Leu-Phe-OH (chemiotactic peptide) and Pro-Leu-Gly-NH2 (MIF) have been carried out. OBg esters are compatible with commonly used protectinggroups and are cleanly and selectively removed in mild alkaline conditions
