Abstract

The stereoselective synthesis of orthogonally protected 3-azido aspartic acid derivatives is described. The convenience of their application as 2,3-diaminosuccinic acid in peptide chemistry was demonstrated by the incorporation of the nonproteinogenic diamino diacid as a cystine-substitute into the core structure of somatostatin.
