GO for it! An enantiopure galactose oxidase (GO) enzyme model has been synthesized from readily available (R)‐binam and Cu(OTf)2 (see scheme; TEMPO=2,2,6,6‐tetramethyl‐piperidin‐1‐oxyl), and has been effectively used as an efficient chiral catalyst for the oxidative kinetic resolution of secondary alcohols. This is the first chiral copper‐catalyzed oxidative kinetic resolution of racemic benzoins and
大胆试试吧!对映纯半乳糖氧化酶(GO)酶模型已从现成的(R)-比纳姆和Cu(OTf)2(参见方案; TEMPO = 2,2,6,6-四甲基-哌啶-1-氧)合成,并且已有效地用作仲醇的氧化动力学拆分的有效手性催化剂。这是外消旋安息香的第一个手性铜催化的氧化动力学拆分,也是合成高度重要的对映体富集的安息香的最简单方法。
