An unprecedented gold(III)-catalyzed intermolecular dimerization of 2-ethynylanilines possessing terminal triple bond offers a general synthetic pathway to a wide range of highly substituted quinolines.
selective, diverse-oriented syntheses of significant heterocyclic derivatives, we here demonstrate the practical advantages of an alternative methodology under metal-free conditions. Our investigation into the key factors influencing the product selectivity in Brønsted acid-catalysed/mediated reactions of 2-alkynylanilines reveals that different reaction pathways can be directed towards the formation of diverse
