  A palladium-catalyzed one-pot procedure for the regioselective dimerization and cyanation of indoles

  摘要：

  A one-pot method for the regioselective dimerization and cyanation of indoles has been developed. The reaction uses safe and nontoxic K-4[Fe(CN)(6)]center dot 3H(2)O as the cyanating agent which introduces selectively a cyano group into the 3-position of biindoles with high efficiency.

  A palladium-catalyzed synthesis of indole fused α-carbolines (pyridodiindoles) from 2,3′-biindoles and nitriles has been developed. This conversion involves the double C–H activation and cyclization of 2,3′-biindoles with nitriles via C–C and C–N bond formation in a single step. However, C-3 cyanated biindoles were formed through a retro-Mannich pathway when the reaction was carried out with ethyl
