The first successful example of the three‐component coupling of N‐alkylanilines, terminal alkynes, and alcohols was achieved at room temperature by a visible‐light‐mediated copper‐catalyzed photoredox hydrogen‐atom transfer process. This method allows preparation of propargylamines through uniquely selective α‐C−H bond activation of unactivated alkylalcohols. Preliminary studies indicate that formation
N-烷基苯胺,末端炔烃和醇三组分偶联的第一个成功实例是在室温下通过可见光介导的铜催化的光氧化还原氢原子转移过程实现的。该方法允许通过未活化烷基醇的唯一选择性α-CH键活化来制备炔丙胺。初步研究表明,α-氧自由基的形成是有效的。这种方法有助于从甲醇中快速获取具有重要生物学意义的炔丙基胺作为丰富的原料。
