anion of enantiopure chiral auxiliary (1R,2S,5R)-(-)-methyl (S)-p-toluenesulfinate to afford C-4 substituted and enantiopure congeners of medicinally potent Biginelli dihydropyrimidinones. The calcium channel blocking activity of some of the compounds was evaluated and compared with nifedipine for their ability to relax a membrane depolarization induced contraction.
