We report a general, catalyst-controlled route to prostaglandin F2_α and its analogues. The approach uses a Rh-catalyzed dynamic kinetic asymmetric Suzuki–Miyaura coupling reaction between a racemic bicyclic allyl chloride and alkenyl boronic esters bearing chiral alcohols to give cyclopentyl intermediates bearing 3 contiguous stereocenters. The route provides advanced intermediates in 99% ee as a single diastereoisomer in all cases examined, with the absolute stereochemistry of the cyclopentane core controlled by the ligand. Intermediates that could be used to produce prostaglandin analogues such as bimatoprost, latanoprost, fluprostenol, and cloprostenol were synthesized. The final two stereocenters were installed via Pd-catalyzed Tsuji–Trost alkylation and iodolactonization. The synthesis of PG F2_α was achieved in 19% yield in 16 longest linear steps.

前列腺素 F2α 的一般催化剂控制途径

_{我们报告了前列腺素 F2 α}及其类似物的一般催化剂控制途径。该方法在外消旋双环烯丙基氯和带有手性醇的烯基硼酸酯之间使用 Rh 催化的动力学不对称铃木 - 宫浦偶联反应，得到带有 3 个连续立构中心的环戊基中间体。在所有检查的情况下，该路线提供 99% ee 的高级中间体作为单一非对映异构体，环戊烷核心的绝对立体化学由配体控制。合成了可用于生产前列腺素类似物（如比马前列素、拉坦前列素、氟前列醇和氯前列醇）的中间体。最后两个立体中心是通过 Pd 催化的 Tsuji-Trost 烷基化和碘内酯化安装的。PG F2的合成在 16 个最长的线性步骤中以 19% 的收率实现了_{α 。}
