Abstract In the context of the methanolysis procedure for sugaranalysis, several alditols were investigated for their capacity to form anhydro derivatives in m methanolic HCl (24 h, 85°). Xylitol, d -arabinitol, l -fucitol, d -glucitol, galactitol, 2-acetamido-2-deoxy- d -galactitol, and the alditols of N -acetylneuraminic acid were very prone to form anhydrides, whereas 2-amino-2-deoxy- d -galactitol
Abstract A new approach towards simple aldonic acid derivatives starting from the corresponding aldoses via the 2-acetamido-2-deoxy formazans resulted in the synthesis of 2-acetamido-2-deoxy- d -galactono-1,4-lactone (8), and its 6-deoxy (11) and 6-azido-6-deoxy (14) analogues on treatment with trifluoroacetic acid.

The present invention provides an immunity inducer and an immunity inducing method using same. The immunity inducer has an immunopotentiation effect on any target oligosaccharide antigen, in particular oligosaccharide antigens included in mammal-derived glycoprotein N-linked sugar chains; is capable of providing a monoclonal antibody having high specificity to and affinity with target oligosaccharide antigens; and has as an effective component thereof a glycolipid including a target oligosaccharide antigen (R) and indicated by general formula (2), or a salt thereof.

conditions of acidhydrolysis, acetolysis, and methanolysis, 2-acet-amido-2-deoxy-, and 2-deoxy-1,3,4,5,6-penta- O -methyl-2-( N -methylacetamido)- d glucitol and - d -galactitol undergo O -demethylation, the N -methyl group being preserved. Upon acetylation, mainly 2-acetamido-I- O -acetyl-2-deoxy-, and 1- O -acetyl-2-deoxy-3,4,5,6-tetra- O -methyl-2-( N -methylacetamido)hexitol derivatives are formed
