Inhibition of gibberellin biosynthesis in Gibberella fujikuroi by 19-norgibberell-16-enes

Methyl ent-7-hydroxy-4 beta (H)-19-norgibberell-16-en-20-oate, the corresponding 7,20-diol and 20-desoxy derivative, have been prepared from gibberellins A sub(13) and A sub(14), respectively. They were not significantly metabolized by Gibberella fujikuroi although a small amount of the 7,14,20-trio...

Zusammenfassung:Methyl ent-7-hydroxy-4 beta (H)-19-norgibberell-16-en-20-oate, the corresponding 7,20-diol and 20-desoxy derivative, have been prepared from gibberellins A sub(13) and A sub(14), respectively. They were not significantly metabolized by Gibberella fujikuroi although a small amount of the 7,14,20-triol was obtained from the 7,20-diol. However, they acted as inhibitors of gibberellic acid biosynthesis.
