heterocycles is a privileged skeleton due to their outstanding catalytic properties and bioactivities. However, their enantioselective synthesis is still underdeveloped. Here we demonstrate the use of easily accessible racemic H–P(O) compounds as starting materials and commercial chiral N1, N2‐dimethyl‐1,2‐diphenylethane‐1,2‐diamine ligand in combination with Cu(I) catalysts to enable an attractive dynamic
P-立体苯并稠合杂环由于其出色的催化性能和生物活性而成为一种特殊的骨架。然而,它们的对映选择性合成仍不发达。在这里,我们演示了使用易于获得的外消旋 H-P(O) 化合物作为起始材料和商业手性 N1,N2-二甲基-1,2-二苯基乙烷-1,2-二胺配体与 Cu(I) 催化剂相结合,使一个有吸引力的动态动力学 C(sp2)-P 交叉偶联反应。该方案不仅展示了广泛的底物范围,而且还提供了对各种有用的P-立体五元、六元、七元和八元苯并稠合O、P-含杂环化合物的一般访问,具有良好的高产率和对映选择性。
