S. Cherif et al., A SYNTHETIC APPROACH TO THE GLYCAN CHAIN OF HIGH-MANNOSE TYPE N-GLYCOPROTEIN, Journal of carbohydrate chemistry, 17(8), 1998, pp. 1203-1218
The syntheses of alpha-D-glucopyranose-(1-->3)-D-mannopyranose, methyl
ha-D-glucopyranose-(1-->3)-alpha-D-mannopyranoside and methyl ha-D-gl
ucopyranose-(1-->3)-alpha-D-mannopyranose-( 1--> 2)-alpha-D-mannopyran
oside are reported. High stereoselectivity was observed during the cou
pling of glucose and mannose residues by the use of glucosyl trichloro
acetimidate as donor.
