Abstract An expeditious strategy has been developed for the synthesis of diverse quinolines, indenoquinolines and acridines using KO t Bu‐mediated reaction conditions. The designed process utilizes 2‐aminoaryl carbaldehydes/2‐aminoaryl ketones methyl/methylene group containing as readily available feedstock. chemical transformation was affected at room temperature within a short duration time to obtain N ‐heterocycles yields up 92 %. established also exhibits considerable functional tolerance with an operational simplicity.

Abstract Catalytic hydrogenation/dehydrogenation reactions are one of the most active areas research for synthesis pharmaceuticals and fine chemicals. Despite several efficient homogeneous catalysts that have already been identified, highly heterogeneous remain elusive. Herein, we report an easy convenient wet impregnation method Pd‐nanoclusters supported on ZnO nanoparticles. The catalyst displays a multifunctional role in 2‐aryl quinolines using alcohol 2‐nitrobenzyl as reactants via dehydrogenation/hydrogenation pathway under neat base‐free reaction conditions. exhibits excellent selectivity can be recycled five times without appreciable loss its activity.
