TextSentencer_T4 644-1058 Sentence denotes Coupling of 3,4,6-tri-O-acetyl-2-deoxy-2-phthalimido-alpha-D-galactopyranosyl bromide and 2-(trimethylsilyl)ethyl O-(2,3,6-tri-O-benzyl-beta-D- galactopyranosyl)-(1----4)-2,3,6-tri-O-benzyl-beta-D-glucopyranoside gave a trisaccharide, which after removal of O-acetyl and phthaloyl groups was converted separately, by benzylidenation and dibutyltin oxide-mediated selective benzylation, into two glycosyl acceptors.

TextSentencer_T7 1405-1772 Sentence denotes Glycosylation of (2S,3R,4E)-2-azido-3-O-benzoyl-4-octadecene-1,3-diol with the alpha-trichloroacetimidates gave the corresponding beta-glycosides, which on channeling through selective reduction of the azido group, coupling of the thus formed amino group with octadecanoic acid, O-deacetylation, and saponification of the methyl ester group, gave the title compounds.
