A simple and efficient approach to (+)-nephrosteranic acid from dodecanol as a starting material is described, employing Sharpless asymmetric epoxidation, ring-closing metathesis, and Gilman addition of a vinyl group as key steps. These key reactions allow fast access to trisubstituted γ-butyrolactone. The molecule synthesized exhibits potent antifungal, antibacterial, and cytotoxic activities against
描述了一种以十二烷醇为原料制备 (+)-肾甾烷酸的简单而有效的方法,采用 Sharpless 不对称环氧化、闭环复分解和吉尔曼加成乙烯基作为关键步骤。这些关键反应可以快速获得三取代的 γ-丁内酯。合成的分子对所有测试菌株均表现出有效的抗真菌、抗菌和细胞毒性活性。
