The spiro-epoxide derived from (-)-2-deoxy-scyllo-inosose was converted into the iodide 2, which was directly subjected to elimination conditions, affording the key methylene compound 4. Successive cyclohexylidenation of the tetrol obtained from 4, select

The synthesis of (+)-valiolamine and (-)-1-epi-valiolamine using bioconversion of (-)-vibo-quercitol was investigated. The quercitols were separated and purified by combination of chromatography on ion-exchange-resin columns and recrystallization. Valiolamine was isolated from fermentation broth of antibiotic validamycins. The obtained crude ketone was subjected to C-C bond formation conditions in which diazomethane was considered adequate in polar and protic solvsnts.
