Synthesis of new tetrazolyl derivatives of L- and D-phenylalanine

Abstract

New tetrazolyl derivatives of L- and D-phenylalanine were synthesized by azidation of n-propyl esters of (2S)- and (2R)-2-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-3-(4-aminophenyl)propionic acids and by a series of subsequent chemical transformations. The structure and individuality of the compounds obtained were confirmed by using a complex of spectral and chromatographic methods.
