摘要

芳基乙胺是药物化合物中的一种特殊支架,是许多医疗药物(包括用于治疗神经系统疾病和疼痛的药物)的骨架。它们的生物医学意义激发了新的合成方法,这些方法依赖于过渡金属催化的烯烃氨基芳基化反应,通常与光氧化催化剂或光敏剂一起进行,并由定向或稳定基团引导。在此,我们介绍一种在无过渡金属条件下对未活化烯烃进行叠氮芳基化的简单而有效的方法。用可见光或近紫外光照射现成的三芳基二氯化铋,会产生一个芳基自由基,选择性地与烯烃发生加成反应,生成的均苄基自由基会被等效的胺截获。这种方法提供了广泛的底物范围,还可以对未活化的烯烃进行芳基氯化和芳基氰化。

Transition metal-free difunctionalization of unactivated alkenes: Arylation/azidation, arylation/chlorination, and arylation/cyanation
Arylethylamines represent a privileged scaffold in pharmaceutical compounds and form the backbone of many medical drugs, including those used for treating neurological diseases and pain. Their biomedical significance has inspired new synthetic methods that rely on transition metal-catalyzed aminoarylation reaction to an alkene, often in conjunction with a photoredox catalyst or a photosensitizer and guided by a directing or stabilizing group. Here, we introduce a simple and effective method for the azidoarylation of unactivated alkenes under transition metal-free conditions. Visible- or near-UV-light irradiation of readily available triarylbismuth dichlorides generates an aryl radical that selectively adds to the alkene, and the resulting homobenzyl radical is intercepted by an amine equivalent. This method offers a broad substrate scope and also enables the arylchlorination and arylcyanation of unactivated alkenes.
