All systems Ar go: A novel approach for the synthesis of 3,3-disubstituted oxindoles was developed using a rhodium-Josiphos chiral catalyst system. This unusual enantioselective rhodium-catalyzed reductive arylation, which functions across a range of substrates, serves as an alternative to palladium(0)-catalyzed α-arylation and does not require the use of a strong base for enolate formation.
