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
Methyl 4-(3-deoxy-L-glycero-tetronamido)-4,6-dideoxy-2-O-methyl-alpha-D- mannopyranoside was acetylated, and the fully protected methyl glycoside was treated with dichloromethyl methyl ether-ZnCl2 (DCMME-ZnCl2) reagent to give 3-O-acetyl-4-(2,4-di-O-acetyl-3- deoxy-L-glycero-tetronamido)-4,6-dideoxy
