ABSTRACT:
4-Phenyl-3-substituted 1,4-dihydropyridine esters are prepared by reaction of benzaldehydes with ketoesters and enamines, if appropriate with isolation of the ylidene intermediate products, or by esterification of corresponding dihydropyridinecarboxylic acids with alcohols.
The new 4-phenyl-3-substituted 1,4-dihydropyridine esters can be employed as active compounds in medicaments for the treatment of the central nervous system, in particular as cerebral therapeutics.
