THE BIOTRANSFORMATION OF TWO ENT-15β,16β-EPOXY-KAURANE DERIVATIVES BY GIBBERELLA FUJIKUROI

The microbiological transformation of the diterpene ent-15β,16β-epoxy-14α-hydroxykaurane into ent-14α,15β-dihydroxy-11α,16α-epoxykaurane, ent-7α,14α,15β-trihydroxy-11α,16α-epoxykaurane and ent-7β,14α,15β-trihydroxy-11α,16α-epoxykaurane has been carried out using the fungus Gibberella fujikuroi.The incubation with this fungus of sideroxol (ent-7α,18-dihydroxy-15β,16β-epoxykaurane) gave as main products ent-7α,15β,18-trihydroxy-11α,16α-epoxykaurane and ent-7α,13,18-trihydroxy-15α,16α-epoxykaurane.Some of these compounds were identified as their acetate derivatives.The presence of the 15α,16α-epoxy group in these two substrates inhibits transformations involving oxidation at C-9 and favours the hydroxylation at C-11(β).

THE MICROBIOLOGICAL TRANSFORMATION OF SOME ENT-7α,15β-DIHYDROXYKAURENE DERIVATIVES BY GIBBERELLA FUJIKUROI

The microbiological transformation by the fungus Gibberella fujikuroi of ent-7α,15β-dihydroxy-kaur-16-ene gave ent-7α,15β,19-trihydroxy-kaur-16-ene, ent-7α,11α,15β-trihydroxykaur-16-ene, ent-7α,11α,15β,16β,17-pentahydroxy-kaurane and ent-7α,11α,13,15β-tetrahydroxy-kaur-16-ene. ent-7α,15β,18-Trihydroxy-kaur-16-ene (eubotriol) afforded ent-7α,11α,15β,18-tetrahydroxy-kaur-16-ene, ent-7α,15β,18,19-tetrahydroxy-kaur-16-ene, ent-7α,17,18-trihydroxy-15β,16β-epoxy-kaurane (epoxysideritriol), and ent-7α,17,18,19-tetrahydroxy-kaur-15-ene.The last three compounds were identified as their acetate derivatives.Key Word Index - Gibberella fujikuroi; microbiological transformations; diterpenes; ent-7α,15β-dihydroxy-kaur-16-ene; eubotriol.
