(R)-Amination mediated by (R)-specific ω-transaminases generally requires costly d-alanine in excess to obtain the desired chiral amines in high yield. Herein, a one-pot, trienzymatic cascade comprising an (R)-specific ω-transaminase, an amine dehydrogenase, and a formate dehydrogenase was developed for the economical and eco-friendly synthesis of (R)-chiral amines. Using inexpensive ammonium formate as the
由(R)-特异性ω-转氨酶介导的(R)-胺化通常需要过量的昂贵的d-丙氨酸以高产率获得所需的手性胺。本文中,开发了包含(R)-特异性ω-转氨酶,胺脱氢酶和甲酸酯脱氢酶的一锅三酶级联反应,以经济和环保地合成(R)-手性胺。使用廉价的甲酸铵作为唯一的牺牲剂,已建立的级联系统实现了各种酮的高效ω-转氨酶介导的(R)胺化,具有高转化率和优异的ee(> 99%);水和二氧化碳是唯一的废物。
