Abstract: | A palladium‐catalyzed cascade reaction based on the trapping of transient alkyl–PdII intermediates with arynes encompassing a C?H activation step has been developed. This synthetic pathway gives rise to hetero‐spirocyclic scaffolds containing a biaryl motif, and opens up new synthetic strategies in the design of cascade reactions since it gathers several aspects of Pd chemistry, i.e., intra‐ and intermolecular carbopalladation of unsaturated species, C?H activation and C?C coupling processes. |
