A copper-promoted intramolecular C–H oxidative amination reaction between secondary amine (N–H) and C(sp3)–H at the benzylic position of azaarenes or α-position of ketones for the synthesis of aziridine derivatives has been developed. Moreover, a practical annulation of electron-deficient vinylarenes with an unprotected primary alkyl amine by a Yb(OTf)3–CuI relay system has also been reported. The
在氮杂芳烃的苄基位置或酮的α位上的仲胺(NH )与C(sp 3)-H之间的铜促进的分子内CH-H氧化胺化反应已经开发出来,用于合成氮丙啶衍生物。此外,也已经报道了通过Yb(OTf)3 -CuI中继系统用未保护的伯烷基胺对缺电子的乙烯基芳烃进行实际的环氧化反应。用氧气作为唯一氧化剂进行反应,以高收率得到N-烷基-和N-芳基氮丙啶。
