bond scission with conjunctive cross‐couplings, this decarboxylative reorganization reaction features fascinating atom and step economy and provides an efficientapproach to highlyfunctionalized dienynes from readily available substrates. Without further optimization, gram‐scale products can be easily obtained by such a simple, neutral, and low‐cost catalytic system with high TONs. DFT calculations
A novel asymmetric catalysis via a palladium(II)/palladium(IV) cycle has been developed by utilizing a chiral spiro bis(isoxazoline) ligand (SPRIX). Intramolecular chlorinative cyclization of 1,6‐enynescatalyzed by a palladium‐SPRIX complex proceeded enantioselectively to afford α‐methylene‐γ‐lactone derivatives.
