摘要：

Electron-rich arylstannanes were found to couple with alpha-iodoenones in the presence of Pd-2(dba)(3) CHCl3, a weak-coordinating ligand [AsPh(3) or Pd(o-tol)(3)] and CuI (0.75-1.0 equiv) to give sterically hindered alpha-arylcyclohexenones 15-20. In addition, compounds 19, 22 and 23 were prepared by Suzuki coupling reactions of the cyclohexyl derivatives 7c,f and 11, respectively, with the arylboronic acid 21.
