| Abstract: | ent-15α-Hydroxykaurenoic acid (8) was synthesized and fed to a mycelium suspension of Gibberella fujikuroi in the presence of 1-n-decylimidazole, a gibberellin biosynthesis inhibitor. The metabolites included 15β-hydroxy GA24, GA45 (GA of Pyrus communis), 15β-hydroxy GA15 and 15β-hydroxy GA25. Microbial production of 12α-hydroxy GAs from ent-12β-hydroxykaurene is also described. |
