摘要：

Gibberellic acid has been transformed into 14beta-hydroxy-gibberellin A7 methyl ester via the rearrangement of an epoxy-beyergibberellin intermediate using a titanium-amide complex. The diterpene ent-beyer-15-en-19-ol has been transformed by chemical methods into ent-14alpha,19-dihydroxy-kaur-16-ene. The biotransformation of this compound with the fungus Gibberella fujikuroi gave 14beta-hydroxy-gibberellin A7, ent-7alpha, 14alpha, 19-trihydroxy-kaur-16-ene and ent-6alpha,7alpha, 14alpha-trihydroxy-kaur-16-en-19-oic acid. A minor gibberellin 14beta-hydroxy-GA14 was identified by GC-MS.
