SYNTHESIS OF 3- AND 2'-FUCOSYL-LACTOSE AND 3,2'-DIFUCOSYL-LACTOSE FROM PARTIALLY BENZYLATED LACTOSE DERIVATIVES

O-β-D-Galactopyranosyl-(1->4)-O-3)>-D-glucose has been synthesized by reaction of benzyl 2,6-di-O-benzyl-4-O-(2,3,4,6-tetra-O-benzyl-β-D-galactopyranosyl)-β-D-glucopyranoside with 2,3,4-tri-O-benzyl-α-L-fucopyranosyl bromide in the
