trifluoromethyl and di-ethoxyphosphoryl groups, has been demonstrated. Using X-ray diffraction analysis, it was found that in some cases of the three-component condensation under study a mixture of 1-aryl-2-amino- and 2-arylamino-substituted products was formed. Migration of the multiple bond onto the ring fused with the dihydropyridine ring has been inferred from the NMR spectra and X-ray diffraction data
