Abstract New and stereoselective syntheses of (1,2,3/4)-, (1,2/3,4)-, (1,4/2,3)-, and (1,2,4/3)-cyclohexanetetrols (1, 2, 3, and 4 respectively) are described. The known syn and anti 1,4-cyclohex-2-enediols 9 and 10 were used as starting materials. Diols 9 and 10 were allow to react with OsO4 to directly form 3 and 1 respectively. Diols 9 and 10 were epoxidized with MCPBA, which yielded 4 and 2 after
On bromination with acetyl bromide and acetic anhydride at 130°C, vibo-quercitol (1) gave tetraacetyl 1-bromo-1-deoxy-scyllo-quercitol (2) in 23% yield. Treatment of 2 with sodium azide in an appropriate solvent afforded three azido compounds, from which, by hydrogenation, corresponding three deoxyinosamines were obtained: 1-deoxy-scyllo-2, 5-deoxy-chiro-1 and 1-deoxy-myo-2-inosamine. The latter two are new compounds and their structures were established by their proton magnetic resonance (PMR) spectra and the reaction sequences.
