Methyl ot-isomaltoside and methyl a-isomaltotrioside analogues specifically deoxygenated at position C-2 of various glucopyranosyl units were synthesized by condensation of either 6-0acetyl-3-O-benzoyl-4-O-benzyl-1-O-tert-butyldimethylsilyl-2-deoxy-fl-D-arabino-hexopyranose (trimethylsilyl triflate

Methyl a-isomaltoside and methyl a-isomaltotrioside specifically deoxygenated at position C-3 of various glucopyranosyl units were synthesized by condensation of either 1,6-di-O-acetyl-2,4-di-O-benzyl-3-deoxy-adg-D-ribo-hexopyranose (7) or 1,6-di-O-acetyl-2,3,4-tri-O-benzyl-a,~-D-glucopyranose [medi
Treatment of methyl Ot-D-perosaminide (1) with y-butyrolactone gave the 2'-deoxy analogue of methyl 4,6-dideoxy-4-(3-deoxy-L-glycero-tetronamido)-a-D-mannopyranoside (13), the methyl a-glycoside of the intracatenary monosaccharide repeating unit of the O-polysaccharide of Vibrio cholerae O:1. The an
Methyl 4-azido-4,6-dideoxy-3-O-benzyl-ct-D-mannopyranoside and its analogous 3-O-(4methoxybenzyl) derivative were methylated and the 2-O-methyl derivatives formed were convetted into methyl 4-amino-4,6-dideoxy-2-O-methyl-a-o-mannopyranoside. Reaction of the latter with 3-deoxy-L-glycero-tetronolacto
## Abstract Three trisaccharide derivatives of the type β‐D‐Hex__p__‐(1 → 4)‐β‐D‐Glc__p__NAc(1 → 2)‐α‐D‐Man__p__‐(1 → O)(CH~2~)~7~CH~3~ have been synthesized, with Hex being either glucose (15), 4‐deoxy‐4‐fluorogalactose (20), or 4‐deoxygalactose (27). These trisaccharides have been designed for th
