ABSTRACT:
4-Heterocyclyl-substituted dihydropyridines are prepared by reacting appropriate aldehydes with .beta.-keto esters and aminocrotonic acid esters, or by esterifying 4-heterocyclyl-substituted dihydropyridinecarboxylic acids. The 4-heterocyclyl-substituted dihydropyridines can be employed in medicaments, in particular for the treatment of disorders of the central nervous system.
