Deprotonation of the digitoxigenin lactone moiety with NaH in N-methylpyrrolidone yields an enolate that reacts at the 21- or 22-position depending on the electrophile. Lactone substituted derivatives of digitoxigenin have been prepared and their inhibition of the cardiac Na+ pump and the inotropic effect of some of the compounds have been studied. Structure-activity relationships are discussed in
在N-甲基吡咯烷酮中用NaH对洋地黄毒苷内酯部分进行质子化,生成烯醇化物,该烯醇化物在21位或22位反应,具体取决于亲电试剂。制备了洋地黄毒苷的内酯取代衍生物,并研究了它们对心脏Na +泵的抑制作用以及某些化合物的正性肌力作用。构效关系是根据霍特耶-安扎利模型进行讨论的。
