Abstract The microbiologicaltransformation of ent -kaur-15-ene and of some derivatives by Gibberellafujikuroi into the gibberell-15-ene analogues of GA 3 , GA 7 , GA 13 and GA 16 and into 7,18-dihydroxykaur-15-enolide and the Δ 15 -isomer of fujenal is described.

been found that an equilibrium mixture of kaurene, isokaurene and hibaene, in the ratio of 2:3:5, is produced when either kaurane or hibaene is heated in boiling xylene in the presence of iodine; thus the interconversion between hibaene and kaurene has been achieved. The stereochemistry of the intermediates in the transformation of hibaene to kaurene has been established.
