Herein, we describe a protocol for alkylation reactions of C(sp3)–H bonds with diacyl peroxides by means of a process involving cross-coupling between an alkyl radical and an α-aminoalkyl radical. The mild, catalyst- and additive-free conditions make this protocol superior to previously reported C(sp3)–H alkylation strategies. The protocol was applied to 1,2,3,4-tetrahydroisoquinolines and a tetrahydro-β-carboline
在这里,我们描述了通过涉及烷基和α-氨基烷基之间的交叉偶联的过程,使C(sp 3)-H键与二酰基过氧化物进行烷基化反应的协议。温和,无催化剂和无添加剂的条件使该方案优于以前报道的C(sp 3)–H烷基化策略。该方案适用于1,2,3,4-四氢异喹啉和四氢-β-咔啉衍生物,可以克级进行,表明其可用于后期合成中间体的烷基化。
