ABSTRACT:
The stereospecific synthesis of a glycopeptide using a triply orthogonal protection scheme is described, in particular, the synthesis of N-acetylglucosaminyl-β-[1,4]-N-acetylmuramylmonopeptide and derivatives thereof. The glycopeptide is useful for the preparation of GMDP and related compounds having a glucosaminyl-β-[1,4]-N-acetylmuramic acid disaccharide core.
