We reported a palladium-catalyzed carbamoyl-carbamoylation/carboxylation/thioesterification of alkene-tethered carbamoyl chlorides using Mo(CO)6 as the carbonyl source. The reactions were typically performed with good functional group compatibility and tolerated different nucleophiles (amines, alcohols, phenols, thiols and water), which provided a new access to amidated/esterificated/thioesterificated/carboxylated oxindoles or lactams bearing an all-carbon quaternary stereocenter under CO gas-free conditions. Furthermore, natural product mutation and divergent late-stage derivatization are the important practical features.

A carbamoyl fluoride-enabled enantioselective Ni-catalyzed carbocarbamoylation of unactivated alkenes was developed, providing a broad range of chiral γ-lactams bearing an all-carbon quaternary center in 45-96% yield and 38-97% ee.

We report herein a miscellaneous 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.
