(57) [Summary] [Object] To provide an enzyme-catalyzed polyaddition reaction of a novel amino disaccharide and an amino disaccharide containing the novel amino disaccharide with a chitinase. [Structure] 2-Methyl- {4-O, which is a novel amino disaccharide -[2-acetamido-2-deoxy-β-glucopyranosyl] -1,2-dideoxy-α-glucopyrano} Developed [2,1-d] -2-oxazoline, Chitin and its similar polysaccharides are obtained by subjecting an aminodisaccharide containing the novel disaccharide to an enzyme-catalyzed polyaddition reaction. |
