  Described are the efficient syntheses of beta-galactose-type unsaturated carbasugar amine, N-octyl-4-epi-beta-valienamine (1a, NOEV) and 6-deoxy NOEV (12), starting from (+)-proto-quercitol (2), which is readily provided by the bioconversion of myo-inositol. NOEV is a potent chemical chaperone drug candidate for G(M1)-gangliosidosis. An intermediate alkadiene benzoate was prepared from 2 in five steps, with the key step being a Wittig reaction with an enol ester. The 6-deoxy derivative 12 was conveniently synthesized from the versatile intermediate dibromo compound 6, which was also an intermediate in the synthesis of NOEV. Enzyme inhibition assays demonstrated that 12 possessed stronger inhibitory activity than the parent 1a, suggesting that the C-6 position of the 4-epi-beta-valienamine-type inhibitor could have hydrophobic interactions at the beta-galactosidase active site residues.

  (+)-proto-Quercitol (1) and (-)-vibo-quercitol (2), both of which could be readily prepared by the bioconversion of myo-inositol, were successfully converted into the corresponding 4-methylenecyclohex-5-ene-1,2,3-triol derivatives. These compounds were demonstrated to be suitable precursors, preserving their configurations, for bioactive carba-aminosugars such as the potent chemical chaperone drug candidates, N-octyl-4-epi-beta-valienamine (NOEV, 3) and N-octyl-beta-valienamine (NOV, 4).
