Bio-transformation of gibberellin 20,19-lactones by Rhizopus stolonifer
摘要:
In a study of the stereo-electronic requirements for microbiological hydroxylation by Rhizopus stolonifer, ent-19-hydroxygibberell-16-en-20-oic acid 20,19-lactone, ent-7,19-dihydroxygibberell-16-en-20-oic acid 20,19-lactone and ent-19-hydroxygibberell-16-en-7,20-dioic acid 20,19-lactone 7-methyl ester are shown to be hydroxylated at the 15alpha-position.

Incubation of ent-7,19-dihydroxygibberell-16-en-20-oic acid 20 --> 19-lactone with Gibberella fujikuroi led to hydroxylation at the 3-alpha- and 19-positions and to oxidation of the 7-alcohol.
