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