1,4-Dihydropyridines, processes for their preparation and their use as antithrombotic drugs.

摘要

The present invention refers to 1,4-dihydropyridines,to processes for their preparation and to their use as antithrombotic drugs. Said new 1,4-dihydropyridines have the following general formula (I) <CHEM> wherein R represents hydrogen or a saturated or unsaturated alkyl group, with a linear or branched chain of 1 to 8 carbon atoms, R<1> represents an alkyl radical with a linear, branched or cyclic, saturated or unsaturated chain of 1 to 12 carbon atoms, which may be interrupted by an oxygen or by a 2-(N-salicylamido)ethyl group, n is a number equal to 1 or 2. These 1,4-dihydropyridines are obtained by processes based on the Hantzch reaction or on modifications thereof.
