Abstract:

A glycosylamino acid “cassette”-based synthetic route has been developed for the preparation of vasopressin analogues with glycosylation. This efficient protocol may be utilized in the synthesis of other novel cyclic glycopeptide structures and derivatives.

Key words: Vasopressin, Glycosylation, Cyclic glycopeptide
