我们运用铱/钌顺序催化体系实现手性高烯丙基醇的立体发散性构建。该一锅串联策略以易得的β-二酮和乙烯基碳酸亚乙烯酯(VEC)为起始原料,整合了铱催化的不对称烯丙基取代/逆-克莱森级联反应与后续的钌催化不对称转移氢化(ATH),可便捷地获得一系列高度官能化的手性高烯丙基醇衍生物。这些产物含有非连续的1,3-叔碳/叔碳手性中心,产率中等至优良,立体选择性优异。通过调控四种不同构型的手性Ir/Ru催化剂组合,能够以优异的立体选择性高效获得目标产物的全部四种立体异构体,其中每个手性中心的构型均由两种不同的手性催化剂独立且精确控制。此外,克级规模合成实验以及一系列衍生化转化研究,说明该顺序催化方案的实用性和合成应用潜力。

Iridium/ruthenium sequential catalysis platform has been established for the stereodivergent construction of chiral homoallylic carbinols. This one-pot tandem protocol leverages readily accessible β-diketones and vinyl ethylene carbonate (VEC) as starting materials, integrating an Ir-catalyzed asymmetric allylation/retro-Claisen cascade process and a subsequent Ru-catalyzed asymmetric transfer hydrogenation (ATH). A diverse array of highly functionalized chiral homoallylic alcohol derivatives containing non-contiguous 1,3-tertiary/tertiary stereocenters could be easily obtained in moderate to good yields with excellent stereoselectivity. Fine manipulation of four distinct chiral Ir/Ru catalyst combinations allows facile access to all four stereoisomers of the target products with excellent stereoselectivity, wherein each stereogenic center is independently and precisely governed by the two distinct chiral catalysts. Furthermore, the practicality of this dual-catalytic protocol is demonstrated by gram-scale synthesis, and the versatile downstream derivatization of the obtained chiral homoallylic alcohols solidifies their utility as robust synthetic building blocks for the construction of complex chiral molecular scaffolds.
