1-Methylpiperidin-4-one and its sulfur and oxygen analogues undergo individual facile pseudo four-component reactions with two folds of malononitrile and various aldehydes by using ultrasonic irradiation and deficient quantities of pyrrolidine. As a conse

A series of 6-amino-8-aryl-2-methyl-1,2,3,4-tetrahydroisoquinoline-5,7- dicarbonitriles were prepared in good yields under solvent-free conditions by multicomponent reactions of aromatic aldehyde, malononitrile, and 1-methylpiperidin-4-one in the presence of sodium hydroxide (NaOH). The structures of the products were characterized by infrared, 1H NMR spectra, elemental analysis, and high-resolution mass spectrometery (HRMS).

A spontaneous reaction takes place between benzaldehydes, malononitrile and N-methyl-4-piperidone to yield the compounds 1a-i which can be aromatized to the new dicyano-1,2,3,4-tetrahydroisoquinolinamines 2a-e.Tetrahydro-2,7-naphtyridines 3a,b were also i
