Double intra, from linear to spiro: A Pd‐catalyzed domino sequence involving an intramolecular aminopalladation followed by arylation that convert linear anilides 1 into the functionalized spiropyrrolidine‐3,3′‐oxindoles 2 in good to excellent yields is presented. The use of 2‐di‐tert‐butylphosphino‐2′‐methylbiphenyl as a ligand determines the success of the domino process. A trans‐aminopalladation...
A palladium-catalyzed three-component synthesis of 3-(diarylmethylene)indolin-2-ones has been developed. A sequence of intermolecular N-arylation/intermolecular carbopalladation/C–H activation/C–C bond formation was realized in a one-pot fashion allowing the construction of one C–N bond and two C–C bonds by way of three distinct catalytic cycles.
