cleavage of cyclopropenes via the rearrangement of the cyclopropyl radical to the allyl radical after the addition of a carbon-centered radical with a leaving group onto the strained double bond, leading to 1,3-diene products with the release of the leaving group. This approach represents a reaction mode for carbon-centered radical-mediated functionalization of cyclopropenes with ring cleavage. The
我们设计并开发了组装多取代 1,3-二烯衍生物的总体策略。该方法在将带有离去基团的以碳为中心的自由基添加到紧张的双键上之后,通过环丙基重排为烯丙基来裂解环丙烯,从而导致 1,3-二烯产物释放离去基团。这种方法代表了一种以碳为中心的自由基介导的环丙烯裂解功能化反应模式。转化发生在温和的反应条件下,并显示出高官能团耐受性。这些极具价值且可修饰的 1,3-二烯产品对 HCT116 细胞显示出良好的抗肿瘤活性。
