A series of novel P-chiral monophosphorus ligands exhibit efficiency in asymmetric Suzuki–Miyaura coupling reactions, enabling the construction of an array of chiral biaryl products in high yields and excellent enantioselectivities (up to 96% ee) under mild conditions. The carbonyl-benzooxazolidinone moiety in these chiral biaryl products allows facile derivatization for further synthetic applications
一系列新颖的P-手性单磷配体在不对称Suzuki-Miyaura偶联反应中表现出效率,使得在温和条件下能够以高收率和出色的对映选择性(高达96%ee)构建一系列手性联芳基产品。这些手性联芳基产物中的羰基-苯并恶唑烷酮部分允许容易地衍生化,以用于进一步的合成应用。一项计算研究表明,两个偶联伙伴之间的π-π相互作用可以增强偶联反应的对映选择性。
