The iridium-catalysed enantioselectiveintramolecularallylicsubstitution of pyrimidine-tethered allylic carbonates was developed. A wide range of chiral pyrimidine-fused diazepinonederivatives were successfully constructed in 88–96% yields with 85–99% ees. This work further highlights the power of chiral-bridged biphenyl phosphoramidites in asymmetric synthesis.
开发了铱催化的对映选择性分子内烯丙基取代嘧啶系烯丙基碳酸酯。以 88-96% 的产率和 85-99% 的 ees 成功构建了多种手性嘧啶稠合的二氮杂酮衍生物。这项工作进一步突出了手性桥连联苯亚磷酰胺在不对称合成中的作用。
