  Application of Rh(I)-Catalyzed C−H Bond Activation to the Ring Opening of 2-Cycloalkenones in the Presence of Amines

  摘要：

  Herein described is the application of the Rh(1)-catalyzed C-H bond activation to the ring-opening of 2-cycloalkenones in the presence of cyclohexylamine. This reaction includes the C-C double bond cleavage of 2-cycloalkenones through the conjugate addition of cyclohexylamine followed by the retro-Mannich-type fragmentation. The resulting ring-opened intermediates subsequently underwent either chelation-assisted hydroacylation to afford a ring-opened dicarbonyl compound or beta-alkylation via a ring contraction.
