A novel dehydrodimerization of malonates with indoles has been developed, providing simple and rapid access to 3-indolyl tetramethyl 1,1,2,2-ethanetetracarboxylates. Pd(OAc)(2)-catalyzed 'one pot' C(sp(2))-C(sp(3)) and C(sp(3)) C(sp(3)) cross-dehydrogenative-couplings of malonates with a variety of 2-aryl indoles were involved. The titled compounds were obtained in high yields with good functional group tolerance. (C) 2016 Elsevier Ltd. All rights reserved.
