N–N axially chiral skeletons are significant structural motifs in natural products, pharmaceuticals, and functional materials. Herein we disclose a method for the asymmetric synthesis of N–N axially chiral compounds by phase-transfer catalysis. A wide range of N–N axially chiral quinazolinone derivatives were prepared in high yields with excellent stereoselectivities. Furthermore, the synthetic utility
N-N 轴向手性骨架是天然产物、药物和功能材料中的重要结构基序。在此,我们公开了一种通过相转移催化不对称合成 N-N 轴向手性化合物的方法。以高产率制备了多种 N-N 轴向手性喹唑啉酮衍生物,具有优异的立体选择性。此外,该协议的合成效用通过产物的大规模反应和转化得到证明。密度泛函理论计算提供了对该机制的深入了解。
