Nitroarenes are reductively cyclized with an array of tetraalkylammonium halides and trialkylarnmonium chlorides in the presence of a catalytic amount of a ruthenium catalyst along with tin(II) chloride dihydrate at 180° to afford the corresponding quinolines in moderate to good yields. The addition of tin(II) chloride dihydrate is necessary for the effective formation of quinolines and toluene is
A convenient and efficient synthesis of substituted quinolines via a simple one-pot reaction of an aniline, an aromatic aldehyde, and an enolizable aliphatic aldehyde in the presence of the iridium catalyst [IrCl2H(cod)]2 under oxygen as an oxidant was developed. The reaction proceeds with Mannich-type imine formation followed by nucleophilic addition to give β-amino aldehydes. Dehydrative cyclization takes place to give dihydroquinoline, which is then dehydrogenated by aerobic oxidation to give 2-aryl-3-alkylquinolines. Dialkylquinolines were obtained by the reaction with anilines and aliphatic aldehydes in good yields.
