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