Abstract
AbstractAn expedient and efficient carbonylative protocol proceeded via palladium‐catalyzed tandem cyclic ketonization and carbonylative spirolactonization has been developed. This carbonylation reaction is compatible with a wide range of hydroxyalkyl ketone tethered benzyl chlorides bearing different functional groups and can be proceeded under comericially available Pd2(dba)3/BINAP catalyst system, providing a straithfowrd and practical approach to a broad range of [6,6]‐oxaspirolactones. The synthesized [6,6]‐oxaspirolactones are commonly found as core structures in natural products and can potentially serve as C2‐symmetric ligand synthons.
