A new one-pot synthetic protocol, enabling the facile access to 2-alkylaminoquinolines and 1,8-naphthyridines by successive ruthenium-catalyzed dehydrogenative annulation and N-alkylation processes, has been demonstrated. A series of 2-aminoarylmethanols were efficiently converted in combination with different types of nitriles and alcohols into various desired products in moderate to excellent yields after isolation. Advantageously, the synthesis proceeds with high atom-efficiency, broad substrate scope, operational simplicity, no need for external hydrogen sources and less environmentally benign halogenated reagents, thus offering a practical approach to access these two types of compounds that are currently difficult to prepare with the conventional methods.

An efficient ruthenium-catalyzed N-alkylation of amines, amides and sulfonamides has been developed employing novel pentamethylcyclopentadienylruthenium(ii) complexes bearing the methylene linked bis(NHC) ligand bis(3-methylimidazol-2-ylidene)methane. The

A simple synthetic strategy has been developed for the synthesis of 2- and 1-alkyl/aryl/dialkylaminoquinolines and isoquinolines from the easily available quinoline and isoquinoline-N-oxides, different amines, triflic anhydride as activating agent and ace
