Herein, we report the copper-catalyzed dehydrogenative C(sp2)–N bond formation of 4-pentenamides via nitrogen-centered radicals. This reaction provides a straightforward and efficient preparation method for γ-alkylidene-γ-lactams. Notably, we could controllably synthesize α,β-unsaturated- or α,β-saturated-γ-alkylidene-γ-lactams depending on the reaction conditions.
在此,我们报道了铜催化通过以氮为中心的自由基形成 4-戊烯酰胺的脱氢 C(sp2)-N 键。该反应为γ-亚烷基-γ-内酰胺的制备提供了一种简单有效的方法。值得注意的是,我们可以根据反应条件可控地合成α,β-不饱和或α,β-饱和-γ-亚烷基-γ-内酰胺。
