A stereodivergent Csp3−Csp3 coupling of 1,3-dienes with oxindoles was achieved by synergizing a palladium and a chiral phase-transfer catalyst in a biphasic system. Both the syn and anti products, which have vicinal quaternary and tertiary stereocenters, could be selectively achieved in good yields with high enantio- and diastereoselectivities. This is the first stereodivergent synthesis via metal/phase-transfer
