Mannopyranoside methyl 3-acetamido-3,6-dideoxy

The paradigmatic hexosaminidase inhibitor with basic nitrogen in the ring, 2-acetamido-1,2-dideoxynojirimycin (2-acetamido-l,2,5-trideoxy- 1,5-imino-D-glucitol, 33) has not been found naturally to date. This inhibitor was first prepared by Fleet and co-workers [76,77] in a 17-step synthesis from D-glucose via methyl 3-0-benzyl-2,6-dideoxy-2,6-imino-a-D-mannopyranoside together...
