Abstract


N-(p-Toluenesulfonyl)glycine o-phenolamide (3a) and the analogous derivatives of d,l-alanine (3b), l-valine (3c), l-leucine (3d), and l-phenylalanine (3e) were synthesized in yields >80% by condensation of N-(p-toluenesulfonyl)amino acyl chlorides with o-aminophenol. The structure and conformation of these amides were established by NMR spectroscopy and X-ray crystallography.
