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)
wherein
R represents hydrogen or a saturated or unsaturated alkyl group, with a linear or branched chain of 1 to 8 carbon atoms, R¹ 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.
本发明是指1,4-二氢吡啶类化合物、其制备工艺及其作为抗血栓药物的用途。 所述新的1,4-二氢吡啶类化合物具有以下通式(I),其中R代表氢或饱和或不饱和烷基,具有1至8个碳原子的线性或支链,R¹代表烷基,具有1至12个碳原子的线性、支链或环状饱和或不饱和链,可被氧或2-(N-水杨酰胺基)乙基基团打断,n是等于1或2的数字。这些1,4-二氢吡啶类化合物是通过基于汉茨反应或其改进的工艺获得的。
