Novel arylsulfonyl-dihydropyridine derivatives which are useful as calcium entry-blocker cardiovascular agents have the formula: ##STR1## or a pharmaceutically acceptable salt thereof, wherein R.sup.1 is hydrogen, lower alkyl, or lower alkoxyalkyl; R.sup.2 is hydrogen or chloro; and R.sup.3 is hydrogen, lower alkyl, or lower alkoxyethyl. A novel process using chiral sulfoxide reagents efficiently produces single isomers of these and other sulfonyl dihydropyridines.
新颖的芳基磺酰基二氢
吡啶衍生物可作为
钙通道阻滞剂心血管药物,其
化学式为:##STR1##或其药用可接受的盐,其中R.sup.1为氢、较低烷基或较低烷氧基烷基;R.sup.2为氢或
氯;R.sup.3为氢、较低烷基或较低烷氧乙基。一种新颖的过程利用手性亚砜试剂高效产生这些和其他磺酰基
二氢吡啶的单异构体。
