✦ Synopsis

Synthesis of two trisaccharides and a tetrasaccharide, namely, alpha-Gal-(1-->3)-beta-Gal-(1-->3)-GlcNAc-beta-OBn (6), alpha-Gal-(1-->3)-beta-Gal-(1-->4)-GlcNAc-beta-OBn (9) and alpha-Gal-(1-->3)-beta-Gal-(1-->4)-GlcNAc-beta-(1-->6)-GalNAc- alpha-OBn (19) was accomplished through development and utilization of a key alpha-galactosyl donor, methyl 2,3,4,6-tetra-O-(4- methoxybenzyl)-1-thio-beta-D-galactopyranoside (1).
