Rings à la carte: Rhodium carboxylate complexes catalyze selective cascade reactions to produce a range 2,3‐disubstituted indoles from β,β‐disubstituted stryryl azides. The selective migration of aryl groups appears to originate from a putative phenonium ion reactive intermediate (see scheme).
点菜环:
羧酸铑配合物催化选择性级联反应,从 β,β-二取代
苯乙烯基
叠氮化物产生一系列 2,3-二取代
吲哚。芳基的选择性迁移似乎源自假定的苯鎓离子反应中间体(参见方案)。
