Furfurylamines are important building blocks for the synthesis of many pharmacologically active compounds and polymers. In this work, direct reductive amination of biobased furans to N‐substituted furfurylamines by reductive aminase from Aspergillus oryzae (AspRedAm) was reported. Besides the reductive aminase activity, AspRedAm also showed a promiscuous, yet low alcohol dehydrogenase activity. The
糠胺是合成许多药理活性化合物和聚合物的重要组成部分。在这项工作中,据报道,米曲霉(Asp RedAm)的还原性胺酶将生物基呋喃直接还原为N-取代的糠胺。除了还原性氨基酶活性外,Asp RedAm还显示出混杂的但低醇脱氢酶活性。事实证明,变体W210F是合成N取代的糠胺的良好催化剂。将呋喃转化为目标产品,转化率最高> 99%,选择性最高> 99%。另外,N在制备规模上合成了高达3200的总取代数(TTN)的预取代糠基胺,表明该生物催化路线在合成化学中的适用性。
