Pseudohygrophorone A12, a highly oxygenated cyclohexenone derivative isolated from Hygrophorus abieticola, exhibits anti-fungal activity against several phytopathogenic fungi and oomycete. The first synthesis of both enantiomers of pseudohygrophorones A12 was accomplished starting from an optically active sulfoxide. In our approach, the diastereoselective Michael−aldol cascade reaction was featured as the key step
假hygrophorone A 12,一种从松果Hygrophorus abieticola分离的高度氧化的环己烯酮衍生物,对几种植物病原真菌和卵菌菌素均表现出抗真菌活性。从光学活性的亚砜开始,完成了首次合成的假高潮酮A 12对映异构体的合成。在我们的方法中,非对映选择性Michael-aldol级联反应是关键步骤。
