The preparation of ent-kaur-6,16-diene and ent-18-hydroxykaur-6,16-diene from epicandicandiol and of ent-3β,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-6α,7α-epoxy-3β,18-dihydroxykaur-16-ene was obtained from ent-3β,18-dihydroxykaur-6,16-diene.The possible biosynthetic significance of the 6,7-epoxidation in kaurenolide is noted. -- Key Word Index - Gibberella fujikuroi; ent-kaur-6,16-dienes; ent-6α,7α-epoxy-3β,18-dihydroxykaur-16-ene; kaurenolide biosynthesis.
