The Hantzsch Ester Production in a Water-based Biphasic Medium, Using Infrared Irradiation as the Activating Source
The reaction of a wide number of benzaldehydes (1a-n) with ethyl (2a) or methyl (2b) acetoacetate and aqueous ammonia (3) has been carried out in the absence of an organic solvent, and using for the first time infrared irradiation as the heating mode. Thus, under the green chemistry protocole, the corresponding mono-1,4-dihydropyridines (4a-j) and bis-1,4-dihydropyridines (4k-n) were obtained in good yields and short reaction times.
