isomer of the putative fusicoccin biosynthetic intermediate, i.e., fusicocca-1,10(14)-diene, was isolated for the first time as a main hydrocarbon constituent from the fusicoccin-producing fungus Fusicoccum amygdali, and its stereostructure including absolute configuration was unambiguously confirmed by total synthesis.
(+)-Fusicocca-2,10(14)-diene,假定的fusicoccin生物合成中间体的双键异构体,即fusicocca-1,10(14)-diene,首次作为主要烃组分被分离出产于fusococcin的真菌Fusicoccum amygdali,其立体结构(包括绝对构型)已通过全合成明确证实。
