Abstract

The use of glycals 3 and 4 as precursors to 1,2-anhydrosugars greatly simplifies the installation of a β-linked ceramide glycoside. By permuting the introduction of the ceramide and the sialic acid, one can access the ganglioside GM4 (1) and, by an unexpected regioselective glycosylation, its NeuAc (2→2) Gal positional isomer 10.
