Abstract
The biotransformation by the fungus Gibberella fujikuroi of the diterp ene ent-14alpha,19-dihydroxy-kaur-15-ene gave ent-14alpha,15beta,19-tr ihydroxy-kaur-16-ene, 5beta,19-trihydroxy-11alpha,16alpha-epoxy-kauran e, 16beta-epoxy-7alpha-14alpha,19-trihydroxy-kaurene, ent-7alpha,14alp ha,19-trihydroxy-kaur-15-ene, 4alpha-dihydroxy-15beta,16beta-epoxy-kau ran-19-oic acid, ent-7alpha,14alpha-dihydroxy-kaur-15-en-19-oic acid, 6alpha,7alpha,14alpha-trihydroxy-kaur-15-en-19-oic acid, lpha,14alpha, 15beta-tetrahydroxy-kaur-16-en-19-oic acid and oxy-6alpha,7alpha,14alp ha-trihydroxy-kauran-19-oic acid. The 14beta-hydroxy-15alpha,16alpha-e poxy-GA15 was the sole gibberellin obtained in this incubation.
