1H‐pyrrole. A structurally related compound, cis‐but‐2‐ene‐1,4‐diol, has been utilized as cosubstrate in different alcohol dehydrogenase (ADH)‐mediated bioreductions. In this case, high conversions (91–99%) were observed due to a lactonization process. Both strategies are convenient from both synthetic and atom economy points of view in the production of valuable optically active products.
两个顺式-和反式-丁-2-烯-1,4-二胺已经制备和有效地施加在酶促转氨基反应牺牲共底物。顺式二胺获得了最佳结果。由于5 H-吡咯互变异构成1 H-吡咯,立体选择性转氨过程的热力学平衡转变为胺的形成,通过使用A可以实现高转化率(78-99%)和对映体过量(高达> 99%)。少量的胺供体。此外,当反应进行时,由于1 H-吡咯的聚合反应,观察到了强烈的着色。结构相关的化合物顺式2-丁烯-1,4-二醇已被用作不同醇脱氢酶(ADH)介导的生物还原的共底物。在这种情况下,由于内酯化过程,观察到较高的转化率(91–99%)。从合成和原子经济的角度来看,这两种策略在生产有价值的光学活性产品时都很方便。
