the total syntheses of these compounds featured the construction of the butenolide moiety by asymmetric dihydroxylation followed by Julia–Kocienski type olefin formation and ring-closing metathesis reactions. The absolute configurations of the two natural products were determined by comparisons of specific rotation. A cell-based assay of the synthetic compounds with transfected human embryonic kidney
首次对映选择性合成了一种从越南蘑菇灵芝分离出的类萜类化合物ganomycin I 和相关的类萜类fornicin A。我们全合成这些化合物的方法的特点是通过不对称二羟基化构建丁烯内酯部分,然后是 Julia-Kocienski 型烯烃形成和闭环复分解反应。两种天然产物的绝对构型是通过比旋光度的比较确定的。用转染的人胚胎肾 293 tet-off (E-PR293) 细胞对合成化合物进行的基于细胞的测定表明甘霉素 I 具有细胞毒性,而 fornicin A 具有弱的抗 HIV-1 蛋白酶活性,但没有细胞毒性。
