Rhodium‐Catalyzed Synthesis of 2,3‐Disubstituted Indoles from β,β‐Disubstituted Stryryl Azides

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).
