have been synthesized via the three-component domino reaction of glutaraldehyde and malononitrile with a series of beta-ketoamides under microwave irradiation conditions in the presence of a catalytic amount of Et3N (10 mol%). This reaction represents the first reported process for the facile conversion of a beta-ketoamide to a hydroisoquinoline via a C-N bond cleavage reaction without the need for

A concise and efficient three-component domino reaction has been developed for the synthesis of polyfunctionalized indenopyridine and hydroisoquinoline derivatives via the cleavage of a C–C bond under transition-metal-free conditions. This reaction provides facile access to complex nitrogen-containing heterocycles by simply mixing three common starting materials in EtOH in the presence of 20 mol %
