available R-(+)-propylene oxide and 1,2-epoxy-5-hexene. Our synthesis exploited key Mitsunobu esterification and (E)-selective ring-closing metathesis (RCM) to assemble the macrocycles as well as a Jacobsen hydrolytic kinetic resolution to install the stereogenic centers. Both synthetic compounds were found to display significant cytotoxic activity against seven human cancer cell lines with the IC50 ranges
从已知的甲基2-(2-甲酰基-3,5-二羟基苯基)开始,聚酮化合物天然产物脱氯绿孢子A和D的第一次和收敛的总合成分别以17个最长的线性步骤完成,总产率分别为2.8%和5.4%。乙酸酯和可商购的R -(+)-环氧丙烷和1,2-环氧-5-己烯。我们的合成利用关键的Mitsunobu酯化和(E)-选择性闭环复分解(RCM)来组装大环,并利用Jacobsen水解动力学拆分来安装立体生成中心。发现这两种合成化合物对七种人类癌细胞系均表现出显着的细胞毒性活性,IC 50范围为6.66-17.15μM。
