The microbiological transformation of some ent-kaur-6, 16-dienes by Gibberella fujikuroi
The preparation of ent-kaur-6, 16-diene and ent-18-hydrosykaur-6, 16-diene from epicandicandiol and of ent-3B, 18-dihydroxykaur-6, 16-diene from foliol is described. On incubation with Gibberella fujikuroi ent-kaur-6, 16-diene gave 7-hydroxykaurenolide and 18-hydroxykaur-6, 16-diene afforded 7, 18-dihydroxykaurenolide, whilst ent-6a,7a-epoxy-3B,18-dihydroxykaur-16-ene was obtained from ent-3B,18-dihydroxykaur-6,16-diene. The possible biosynthetic significance of the 6, 7-epoxidation in kaurenolide formation is noted.
