Synthesis of tetrasaccharides as possible metastatic inhibitors.
The synthesis is reported of the possible metastatic inhibitors-methyl beta-D-galactopyranosyl-(1-->4) -(2-acetamido-2-deoxy-alpha-D-glucopyranosyl)-(1-->6) -beta-D-galactopyranosyl-(1-->4)-beta-D-glucopyranoside (11) and methyl beta-D-galactopyranosyl- (1-->4)-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)- (1-->6)-beta-D-galactopyranosyl-(1-->4)-beta-D-glucopyranoside (14)-by procedures for regio- and stereo-selective coupling, reduction of azido groups, N-acetylation, and O-deacetylation.
