The indole alkaloids, ranging from lysergic acid to vincristine, have long inspired organic chemists.Interest in developing new methods for indole synthesis has burgeoned over the past few years.1 Usage of different metal-metal salt combinations2 such as Al-NiC12.6H2O,3 Fe-NiCl2.6H2O, 4 etc., for bringing about useful organic transformation are well known in the literature.Our group also reported the utility of A1-NiC12.6H2O-THF system for conversion of nitoolefines into carbonyl compounds.5 In continuation of our interest in Al-NiCl2.6H2O system, we developed a mild and convenient process for reductive cyclization of 2,β-dinitrostyrene to synthesize a number of indole derivatives.
