New compounds useful as therapeutical agents and useful as intermediates for the preparation of other therapeutically active di-hydropyridines, which new compounds are of the formula
wherein R' in one or two (the same or different) substituents on the phenyl ring selected from the group consisting of NO2, Cl and lower alkyl; R is -CH3, -CHO or
wherein R" and R12 are same or different, straight or optionally branched lower alkyl or both together are part of 5-7 membered ring, provided that when one of R is -CHs the other is -CHO or
wherein R" and R12 have the meaning given above; processes for the preparation of said compounds; pharmaceutical preparations containing said compounds, a method for their therapeutical use and new processes using said compounds as intermediates for the preparation of therapeutically active dihydropyridines.
