The Pd-catalyzed 3-arylation of 2-oxindoles with aryl bromides, chlorides and triflates is found to proceed using i-Pr-BI-DIME and Me2-BI-DIME ligands. The mono-arylation of 3-unsubstituted oxindoles is accomplished using a Pd2(dba)3/i-Pr-BI-DIME catalyst system, and gives good yields of 3-aryloxindoles from aryl bromides and chlorides. The arylation of 3-substituted oxindoles is also possible using this catalyst/ligand system. The asymmetric arylation of 3-substituted oxindoles is accomplished using Me2-BI-DIME to furnish oxindoles bearing a quaternary C-3 stereocenter in enantiomeric ratios of up to 93:7.
