We report herein a CuX2-mediated halocyclization of γ,δ-unsaturated amides for the synthesis of functionalized iminolactones and lactams respectively under mild reaction conditions. Mechanism studies indicated that N-attack cyclization was via a radical route while oxycyclization was via a nucleophilic attack on the activated C=C bond.
我们在此报告一种由CuX2介导的γ,δ-不饱和酰胺的卤环化反应，该反应可在温和的反应条件下分别用于合成官能化的亚胺内酯和内酰胺。机理研究表明，氮原子进攻的环化反应是通过自由基途径进行的，而氧原子进攻的环化反应是通过对活化的碳碳双键进行亲核进攻来实现的。
