• The title new reducing trisaccharides were synthesized starting from 1,6-anhydro-β-maltose. Reflux of 2,2', 3,3', 4'-penta-O-acetyl-1,6-anhydro-β-maltose with 2,3,4,6-tetra-O-benzyl-α-D-galactopyranosyl chloride in benzene in the presence of mercuric cyanide and Drierite stereospecifically afforded the corresponding trisaccharide derivative having α-D-(1→6) galactosidic linkage (yield 63%). After debenzylation with subsequent acetylation, acetolysis of the β-1,6-anhydro linkage, and deacetylation, the former title trisaccharide was obtained. Stirring of 2,2', 3,3', 4'-penta-O-acetyl-1,6-anhydro-6'-O-trityl-β-maltose with 2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl bromide in nitromethane in the presence of silver perchlorate and Drierite, followed by acetylation stereospecifically yielded the corresponding trisaccharide derivative having β-D-(1→6) galactosidic linkage (yield 56%). Acetolysis of the β-1,6-anhydro linkage, followed by deacetylation gave the latter title trisaccharide.
