Abstract
The microbiological transformation of 7alpha,19-dihydroxy-ent-atis-16-ene by the fungus Gibberella fujikuroi gave 19-hydroxy-7-oxo-ent-atis-16-ene, 13(R),19-dihydroxy-7-oxo-ent-atis-16-ene, 7alpha,11beta,19-trihydroxy-ent-atis-16-ene and 7alpha,16beta,19-trihydroxy-ent-atis-16-ene, while the incubation of 19-hydroxy-7-oxo-ent-atis-16-ene afforded 13(R),19-dihydroxy-7-oxo-ent-atis-16-ene and 16beta,17-dihydroxy-7-oxo-ent-atisan-19-al. The biotransformation of 7-oxo-ent-atis-16-en-19-oic acid gave 6beta-hydroxy-7-oxo-ent-atis-16-en-19-oic acid, 6beta,16beta,17-trihydroxy-7-oxo-19-nor-ent-atis-4(18)-ene and 3beta,7alpha-dihydroxy-6-oxo-ent-atis-16-en-19-oic acid.
