Abstract A quick and highly efficient microwave-assisted preparation of imidazopyridines and –quinolines is described, starting from the corresponding ketones and amines. The method requires no solvent and uses activated MnO2 as an oxidant. A mechanism for the cyclization is proposed and discussed. Graphical Abstract
