摘要:
1,4,6-Tri-O-acetyl-2,3-bis(tert-butyloxycarbonamido)-2,3-dideoxy-alpha-D-glucopyranose (8) was prepared through catalytic reduction and in situ tert-butyloxycorbonylation of 1,4,6-tri-O-acetyl-2-azido-2,3-dideoxy-3-nitro-alpha-D-glucopyra?? nose (5). Starting from 8, 4S,5S-bis(3R-hydroxytetradecanamido)octan-1,8-dioic acid (4) was synthesised in a series of steps.
