A novel palladium‐catalyzedC‐7 selectiveCH carbonylation of indolines with carbon monoxide for an expedient synthesis of pyrroloquinazolinediones, a structural motif with great potential in biologically active compounds, has been developed. Oxidation of the pyrroloquinazolinedione with 2,3‐dichloro‐5,6‐dicyano‐p‐benzoquinone (DDQ) could easily afford the corresponding indole‐based derivative in
