The free radical cyclization reaction is a promising strategy for ring framework formation. Herein, we report a copper-catalyzed tandem radical cyclization strategy for preparing substituted lactam derivatives. This reaction proceeds through a radical coupling approach, which not only allows a wide range of alkenes but also is quite compatible with the primary, secondary, and tertiary radicals. In addition
自由基环化反应是一种很有前景的环骨架形成策略。在此,我们报告了一种铜催化的串联自由基环化策略,用于制备取代的内酰胺衍生物。该反应通过自由基偶联方法进行,不仅允许范围广泛的烯烃,而且与伯、仲和叔自由基非常相容。此外,还进行了密度泛函理论计算以深入了解反应机理。
