Microbial transformation of the diterpene 7-epi-foliol by Fusarium fujikuroi

The incubation of 3,7,18-trihydroxy-ent-kaur-16-ene (7-epi-foliol) with the fungus Fusarium fujikuroi gave 3,7,18-trihydroxy-ent-kaur-16-en-18-al as the sole product. The biotransformation of other 7- or 7-hydroxy derivatives had led to the oxidation of C-19, which is a main step in the biosyn...

Sumario:The incubation of 3,7,18-trihydroxy-ent-kaur-16-ene (7-epi-foliol) with the fungus Fusarium fujikuroi gave 3,7,18-trihydroxy-ent-kaur-16-en-18-al as the sole product. The biotransformation of other 7- or 7-hydroxy derivatives had led to the oxidation of C-19, which is a main step in the biosynthesis of gibberellins and kaurenolides. Now, the presence of the 3-hydroxyl impedes that oxidation, which is directed to the adjacent C-18 hydroxymethyl forming the corresponding aldehyde.
