Nickel-BINAP Catalyzed Enantioselective α-Arylation of α-Substituted γ-Butyrolactones
摘要:
A Ni(0)-BINAP system is utilized for the highly enantioselective alpha-arylation of alpha-substituted gamma-butyrolactones with aryl chlorides and bromides. alpha-Quaternization is achieved in moderate to excellent yields. Furthermore, the rate accelerating effect caused by the addition of Zn(II) salts is investigated.
