Abstract
Abstract 2,3,4-Tri- O -acetyl-6- O -(chloroacetyl)-α- d -galactopyranosyl bromide ( 5 ) has been prepared. When condensed with 1,2,3,4-tetra- O -acetyl- d -galactopyranose, it yielded 1,2,3,4-tetra- O -acetyl-6- O -[2,3,4-tri- O -acetyl-6- O -(chloroacetyl)-β- d -galactosyl]- d -galactopyranose ( 6 ). The O -chloroacetyl group could be selectively removed from 6 by treatment with thiourea, and the resulting product was again condensed with 5 , to yield, after deprotection, the trisaccharide title-compound.
