-Alkylidene butenolides bearing a deoxyriboside, a steroid, and a metallocene moiety were synthesized by stereoselective sequential cross-coupling lactonization procedure from the corresponding functionalized terminal alkynes with 3-iodopropenoic acids. The high selectivity of the butenolide ring formation was secured by the Pd/Cu salt ratio. The resulting compounds were tested for antifungal and cytostatic
-具有脱氧核苷、类固醇和茂金属部分的亚烷基丁烯内酯是通过立体选择性顺序交叉偶联内酯化过程从相应的官能化末端炔烃与 3-碘丙烯酸合成的。丁烯内酯环形成的高选择性由 Pd/Cu 盐比保证。测试所得化合物的抗真菌和细胞抑制特性。最值得注意的是,带有脱氧核苷部分的γ-亚烷基丁烯内酯在微摩尔范围内显示出有希望的细胞抑制活性。
