Michael-addition of 3-aminocrotonic acid ester 7 to aralkylidene acetoacetic acid esters 6 is followed by ring closure to give novel 4-aryl-1,4-dihydro-2,6-dimethyl-pyridine-3,5-dicarboxylates 8 with non-identical ester functions. In the series of 3-nitrophenyl derivatives (8, Ar=3-nitrophenyl) the pharmacological activities (coronary vasodilation, anti-hypertensive activity) of the asymmetrically substituted derivatives are shown to be superior to those of the corresponding symmetrically substituted derivatives in many cases. One representative of this class 3-ethyl-5-methyl-1,4-dihydro-2,6-dimethyl-4-(3-nitrophenyl)-3,5-pyridinedica rboxylate (nitrendipine, Bay e 5009, No. 3) was selected for further development as an antihypertensive drug.

1,4-Dihydropyridines of the formula: STR1 wherein R is hydrogen, straight, branched or cyclic lower alkyl, lower alkenyl, or lower alkinyl, unsubstituted or substituted; or benzyl, or phenethyl, unsubstituted or substituted in the aryl portion; R' is alkyl of 1 to 4 carbon atoms; R" is alkenyl of 2 to 6 carbon atoms, alkinyl of 2 to 6 carbon atoms, cyclic alkenyl of 3 to 6 carbon atoms interrupted by oxygen, alkenyl of 2 to 6 carbon atoms or alkinyl of 2 to 6 carbon atoms interrupted by 1 or 2 oxygen atoms, or alkenyl of 2 to 6 carbon atoms or alkinyl of 2 to 6 carbon atoms substituted by hydroxyl; and R'"is unsubstituted or substituted aryl; cyclohexyl; benzyl; styryl; pyridyl; pyrimidyl; furyl; thienyl; pyrrolyl; pyridyl, pyrrolyl, thienyl or furyl substituted by alkyl of 1 or 2 carbon atoms; or substituted pyrimidyl: STR2 are useful for their coronary dilating effect, their nitrite-like effect on the heart, their anti-fibrillation effect, their vascular-spasmolytic effect and muscular-spasmolytic effect, and as anti-hypertensives.
