• Ester Hydrolysis by a Catalytic Cyclodextrin Dimer Enzyme Mimic with a Metallobipyridyl Linking Group

  A β-cyclodextrin dimer with a linking bipyridyl group is synthesized as a catalyst precursor, a holoenzyme mimic. It binds both ends of potential substrates into the two different cyclodextrin cavities, holding the substrate ester carbonyl group directly above a metal ion bound to the bipyridyl unit. The result is very effective ester hydrolysis with good turnover catalysis. For example, a Cu(II) complex

  合成了具有连接联吡啶基团的 β-环糊精二聚体作为催化剂前体，即全酶模拟物。它将潜在底物的两端结合到两个不同的环糊精腔中，将底物酯羰基直接固定在与联吡啶单元结合的金属离子上方。结果是非常有效的酯水解和良好的转化催化。例如，Cu(II) 络合物将几种硝基苯酯的水解速率加快了 104-105 倍，至少有 50 次转换且没有产物抑制的迹象。在最好的情况下，通过添加也与金属离子结合的亲核试剂，观察到比背景反应速率高 1.45 × 107 的速率加速。仅具有一个环糊精结合基团的催化剂的水解速度明显慢于双齿结合情况。正如预期的那样，存在金属离子时，过渡态类似物与这些催化剂的结合比不存在时更强。这个和动力学证据指向一个机制......
