Starting with N-acetyl-D-glucosamine, methyl 2-acetamido-3,6-di-Obenzyl- 2-deoxy-β-D-xylo-hexofuranosid-5-ulose (18) was prepared in 7 steps. The addition reaction of dimethyl phosphonate to 18, followed by deoxygenation of its 5-hydroxy group, provided the 5-deoxy-5-dimethoxyphosphoryl-Dglucofuranoside derivative (21a). The hydride reduction of 21a, followed by the action of hydrochloric acid and then hydrogen peroxide, afforded the first D-glucosamine analog (23) having a phosphoryl group in the hemiacetal ring. This was converted into the per-O-acetylated N-acetyl-D-glucosamine phospha-sugar (25), while the same treatment of the 5-deoxy-5- dimethoxyphosphoryl-L-idose dimethyl acetal derivative (13b) afforded the N-acetyl-L-idosamine phospha-sugar (29).

The furanose acetonide derivative 1 is readily prepared from 2-acetamido-2-deoxy-D-glucose on a large scale without the need for chromatography. Mesylation of 1 provides an efficient, concise, synthetic route to rare 2-acetamido-2-deoxy-β-D-hexopyranosides (2 and 3) via the corresponding methyl 2-acetamido-2-deoxy-3-O-methanesulfonyl-β-D- glucopyranoside and subsequent inversion of configuration by direct displacement or formation of a 3,4-epoxide. Opening of this epoxide by azide provided a direct route to methyl 2-acetamido-4-amino-2,4,6-trideoxy-β-D- gulopyranoside 4. Benzylation of 1 followed by ring expansion to the glucopyranoside, deoxygenation at C-6, and subsequent displacement of a C-4 triflate permitted the synthesis of methyl 2-acetamido-4-amino-2,4,6-trideoxy- β-D-galactopyranoside 5. Methyl 2-acetamido-2-deoxy-β-D- glucopyranoside available from 1 in quantitative yield was readily converted to methyl 2-acetamido-2-deoxy-β-D-galactopyranoside 6 (>60%) by inversion of configuration at C-4. Introduction of a lactyl substituent at C-3 of oxazoline 1 also provides a facile synthesis of the biologically important muramic acid β-glycoside 7. An interesting reaction to convert 2-acetamido-2-deoxyhexopyranosides to the corresponding 2-deoxy-2-tetrazole is also reported.

The title compounds, galacto-1 and gluco-2, were synthesised from N-acetyl-D-glucosamine via a common 1,4-diol intermediate that underwent transformations involving either a single or double inversion of stereochemistry at C-4, respectively. In the double

2-Acetamido-1,2,4-trideoxy-1,4-imino-D-galactitol was synthesised from 2-acetamido-2-deoxy-D-glucose in 12 steps and was shown to be a modest hexosaminidase inhibitor.
