developed with a synergistic Cu-catalyzed Kinugasa system and a Pd-catalyzed allylic alkylation reaction. This unprecedented reaction provides in high yields and with high stereoselectivity a synthesis of α-quaternary chiral β-lactams, which cannot be produced with existing synthetic methods. Stereoselective coupling of two catalytic amounts of transient organometallic intermediates formed in situ is an important
已经开发了不对称多组分间断 Kinugasa 烯丙基烷基化 (IK
AA) 反应,该反应具有协同 Cu 催化的 Kinugasa 系统和 Pd 催化的烯丙基烷基化反应。这种前所未有的反应以高产率和高立体选择性合成了 α-季
铵盐手性 β-内酰胺,这是现有合成方法无法生产的。原位形成的两种催化量的瞬态有机
金属中间体的立体选择性偶联是该反应的一个重要特征。
