A Cu-catalyzed asymmetric thiolative ring opening reaction of five-membered diaryliodonium salts and potassium thioates for the synthesis of atropisomeric 2'-iodo-[1,1'-biphenyl]-2-yl thioates was realized. The optimal catalytic system, Cu(CHCN)PF/(Ph)-bis(oxazoline), showed the best performance with respect to both yields and stereocontrol. Finally, the utility of these products was briefly demonstrated by the synthesis of an axially chiral P,S-ligand.
实现了铜催化的五元二芳基碘鎓盐与硫代钾盐的不对称硫叶立德开环反应,用于合成非对应异构体的 2'-碘-[1,1'-联苯]-2-基硫代酯。最优的催化体系为 Cu(CHCN)PF/(Ph)-双(恶唑啉),在产率和立体控制方面都表现出最佳性能。最后,通过合成轴手性的 P,S-配体,初步展示了这些产物的实用性。
