A highly enantioselective NH insertion reaction of α‐diazoketones was developed by using cooperative catalysis by dirhodium(II) carboxylates and chiral spiro phosphoric acids. The insertion reaction provides a new access route to diverse chiral α‐aminoketones, which are versatile building blocks in organic synthesis, with fast reaction rates, good yields and high enantioselectivity under mild and
羧酸二(II)盐和手性螺环磷酸的协同催化作用,开发了α-重氮酮的高对映选择性的NH插入反应。插入反应为各种手性α-氨基酮提供了一条新的途径,这些手性α-氨基酮是有机合成中的通用组成部分,在温和和中性条件下具有快速的反应速率,良好的收率和高对映选择性。
