title: 3-Azido-aspartic acid derivatives - orthogonally protected precursors for the stereoselective incorporation of 2,3-diaminosuccinic acid into peptide structures.
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.
