A stereocontrolled synthesis of globotriaosylcernmide with three different glycosidic linkages has been accomplished by linear and convergent routes exploiting "armed-disarmed" glycosidation methodology bared on glycosyl donors and accepters carrying tetramethylphosphoroamidate as a leaving group. In particular, the convergent strategy featuring a coupling of a galactosyl-(1-->4)-galactosyl donor with a glucosylceramide derivative has proven to be extremely efficient.
