A palladium-catalyzed selective and successive vinylic C–H arylation/amination of 2-vinylanilines with arylboronic acids to generate indoles has been developed. This procedure represents a straightforward and practical approach to valuable multifunctionalized indoles.
oxindole synthesis bearing an all-carbon quaternary center, enabled by Pd-catalyzed intramolecular cyclization followed by multiple intermolecular Heck reactions of both easily accessible alkene-tethered carbamoyl chlorides and olefins. This protocol obviates the use of prefunctionalized olefinic reagents, exhibits excellent functional group tolerance, and features fascinating reactive versatility.

A cascaderadicaladdition/cyclization reaction of 2‐vinylanilines with alkynes for the synthesis of biologically important naphthalene derivatives is reported. In this transformation, the in‐situ‐formed diazonium salts from 2‐vinylanilines served as efficient aryl radical precursors and the reaction was run under metal‐free conditions.
