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.
1,2-二氢-1,6-二甲基/ 6-甲基-2-氧嘧啶-5-羧酸乙酯与C-亲核试剂以及对映纯手性助剂(1R,2S,5R)-(-)-甲基的阴离子反应(S)-对甲苯磺酸盐,可得到具有药效的比吉内利二氢嘧啶酮的C-4取代对映体和对映体纯同系物。对某些化合物的钙通道阻断活性进行了评估,并与硝苯地平比较了它们舒张膜去极化引起的收缩的能力。
