Epoxidation of ent-pimara-8(14),15-dien-19-oic acid by whole cells of the endophytic fungus Aspergillus sclerotiorum

Abstract The diterpene ent -pimara-8(14),15-dien-19-oic acid ( 1 ) was converted into four oxidized diterpenes, 15,16-epoxy- ent -pimar-8(14)-en-19-oic acid ( 1a ), 15,16-epoxy-17-hydrxy- ent -pimar-8(14)-en-19-oic acid ( 1b ), 15,16-dihydroxy- ent -pimar-8(14)-en-19-oic acid ( 1...
