Efficient catalytic one-step synthesis of substituted quinoline derivatives using newly synthesized Ru(II) half-sandwich complexes of the type [Ru(η6-p-cymene)Cl(L)] (L = pyrrole-2-aldehydehydrazones) under mild conditions is described. The synthesized complexes exhibit excellent catalytic activity towards the coupling of 2-amino alcohol with functionalized ketones and secondary alcohols in the optimal conditions and afforded the corresponding quinoline derivatives. The synthetic pathway proceeds with high atom efficiency via a sequence of acceptorless dehydrogenation and condensation steps. The maximum isolated yield of the product obtained was up to 97% using 0.3?mol% of catalyst loading for 5?h. These findings significantly advance the scope of the synthesis of bioactive heterocyclic compounds from readily available starting materials.
