从异山梨醇或异甘露醇开始,合成了几种基于双脱水己糖醇的苯甲脒作为潜在的 Xa 因子抑制剂。合成双苯甲脒的关键步骤是亲核芳香取代和光延反应以形成苯醚。另一种类型的单苯甲脒具有邻位取代的联苯基。由于邻位取代基的巨大空间位阻,它们的合成需要优化交叉偶联程序。苯甲脒显示出针对 Xa 因子的生物活性以及针对其他丝氨酸蛋白酶的选择性。
Starting with isosorbide or isomannide several dianhydrohexitole-based benzamidines were synthesized as potential factor Xa inhibitors. The key steps for the synthesis of the bisbenzamidines were nucleophilic aromatic substitutions and Mitsunobu reactions to build up phenylethers. Another type of monobenzamidines had ortho-substituted biphenyl groups. Their synthesis necessitated an optimization of cross coupling procedures due to the great sterical hindrance of the ortho-substituent. The benzamidines showed biological activity against factor Xa and selectivity against other serine proteases.
