Abstract
Both C-4 stereoisomers of novel Hantzsch-type 4-aryl- and 4-methyl-1,4 -dihydropyridines 3 having a polylsulfinyl group at C-5 were efficient ly synthesized in optically pure forms starting from the alpha-sulfiny l enones 6 which could be easily obtained from (-)-menthyl (S)-p-tolyl sulfinate (4). The stereochemistry at C-4 was found to be largely resp onsible for the biological activities as calcium channel antagonists o f these compounds.
