Fungal products. Part XII. Gibberellin A14-aldehyde, an intermediate in gibberellin biosynthesis in Gibberella fujikuroi

Abstract

Gibberellin A14-aldehyde (4) has been synthesised from 3β,7β-dihydroxykaurenolide (10). In cultures of Gibberella fujikuroi, mutant Bl-41a, it is shown to be formed from gibberellin A12-aldehyde (1) and to be converted into fungal 3-hydroxylated gibberellins including gibberellin A3(8). Gibberellin A14(6) and gibberellin A14-alcohol (7) are also metabolised to 3-hydroxygibberellins, the former at a much lower rate. The biosynthetic pathway to gibberellins in the fungus is discussed in the light of these results.
