Abstract In the synthesis of modified derivatives of octyl O -(α- d -mannopyranosyl)-(1 → 3)- O -[(α- d -mannopyrasonyl)-(1 → 6)-β- d -mannopyranoside, a 4,5-epoxypentyl, a 4-diazirinopentyl, and a 5-(iodoacetamido)pentyl group were attached to the 3″-OH of the trisaccharide. The diazirino derivative may be especially suitable for photolabeling of the active site of N -acetylglucosaminyltransferase
