  Manganese catalysts derived from tridentate P,N,N ligands can be activated easily using weak bases for both ketone and ester hydrogenations. Kinetic studies indicate the ketone hydrogenations are 0th order in acetophenone, positive order in hydrogen and 1st order in the catalyst. This implies that the rate determining step of the reaction was the activation of hydrogen. New ligand systems with varying

  源自三齿P，N，N配体的锰催化剂可以使用弱碱轻松地活化，以进行酮和酯的加氢反应。动力学研究表明，酮氢化在苯乙酮中为0级，在氢中为正级，在催化剂中为1级。这暗示该反应的速率确定步骤是氢的活化。研究了具有不同供体强度的新型配体体系，这可能使氢活化显着更有效。这些动力学研究的结果是，发现了一种相对于母体系统而言，苯乙酮氢化反应的初始转换频率提高了约3倍的催化剂。酯加氢和酮转移加氢（异丙醇作为还原剂）对于底物和催化剂都是第一级的。动力学研究还获得了对催化剂稳定性的了解，并确定了在整个催化反应中催化剂稳定的工作范围（以及仍然可以实现高收率的更大的工作范围）。新的更具活性的催化剂将富电子膦与富电子吡啶结合使用，能够在65°C的条件下使用低至0.01 mol％的催化剂氢化苯乙酮。总之，描述了还原21种酮和15种酯的方案。将富电子膦与富电子吡啶结合使用能够在低至65°C的条件下使用低至0.01 mol％的

  Despite extensive research on small molecule thrombin inhibitors for oral application in the past decades, only a single double prodrug with very modest oral bioavailability has reached human therapy as a marketed drug. We have undertaken major efforts to identify neutral, non-prodrug inhibitors. Using a holistic analysis of all available internal data, we were able to build computational models and
