The branched trisaccharide glycosides (7) and (8) named in the title have been prepared from 3-(methoxycarbonyl)propyl 3,4-O-(2-nitrobenzylidene)-6-O-pivaloyl-α-D-galactopyranoside (2).Galactosylation of compound (2) afforded the fully protected β-galactosyl-α-galactoside derivative (3) which upon sequential photolysis and oxidation was regioselectively converted into the partially blocked 4-O-(2-nitrobenzoyl)disaccharide (4).Further galactosylation of compound (4) gave a mixture of equal amounts of the di-(β-galactosyl)-α-galactoside derivative (5) and the β-galactosyl-α-galactosyl-α-galactoside derivative (6) which were separated, and these yielded the title compounds upon subsequent deacylation.
