(2) and a revision of its C6 absolute stereochemistry (1) are described. Amphidinolide W (1), a 12-membered macrolide isolated from Amphidinium sp., has shown potent antitumor properties against a variety of NCI tumor cell lines. The synthesis is convergent, and four of the five chiral centers were derived through asymmetric synthesis. The synthesis features Sharpless asymmetric dihydroxylation, diastereoselective
描述了对映选择性首次全合成的双环内酯 W (2) 及其 C6 绝对立体化学 (1) 的修订。Amphidinolide W (1) 是一种从 Amphidinium sp. 中分离出来的 12 元大环内酯,已显示出对多种 NCI 肿瘤细胞系的有效抗肿瘤特性。合成是收敛的,五个手性中心中有四个是通过不对称合成得到的。该合成具有 Sharpless 不对称二羟基化、非对映选择性烷基化、官能化底物的有效交叉复分解以及使用选择性脂肪酶催化水解初级乙酸酯基团的新型官能团转化。特别值得注意的是,amphidinolide W (1) 的 C6 绝对立体化学现已通过我们当前的合成进行了修订。
