[Figure not available: see fulltext.] A one-pot tandem synthesis of substituted quinolines involving selective catalytic oxidation of primary alcohols to the corresponding aldehydes and their subsequent condensation with arylamines has been developed. Fe(CrO2)2 has been used as a catalyst, and oxidation has been performed with aqueous H2O2. To accelerate the catalytic oxidation of alcohols, photoactivation method has been applied.

One-pot tandem synthesis was developed for substituted quinolines (in up to 97% yields) involving a selective catalytic oxidation of primary amines to aldehydes and their condensation with arylamines under the action of a dispersion of Fe(CrO2)2 and water solution of H2O2 at room temperature. The stage of catalytic oxidation of alcohols was accelerated by photoactivation. A presumable mechanism of the photoactivated tandem synthesis of 2-methylquinoline was suggested. Catalyst Fe(CrO2)2 was prepared by photochemical synthesis.

A versatile heterogeneous catalyst consisting of sub-nanosized iridium clusters deposited on titania (Ir/TiO2-NCs) promotes the direct tandem synthesis of quinoline derivatives from readily available nitroarenes and aliphatic alcohols under mild and additive-free conditions (see scheme). The process tolerates the presence of various reactive functional groups and is highly selective.
