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.
