Abstract:In a study of the stereo-electronic requirements for microbiological hidroxylation 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-lactome 7-methyl ester are shown to be hydroxylated at the 15$-position.
