  Prunus armeniaca hydroxynitrile lyase (ParsHNL)-catalyzed asymmetric synthesis of cyanohydrins from sterically demanding aromatic aldehydes

  摘要：

  Herein we report the biocatalytic asymmetric synthesis of cyanohydrins by using a new (R)-HNL from Prunus armeniaca. Several sterically demanding aromatic aldehydes which have never been used as substrates for any known HNLs are employed for the new (R)-HNL from A armeniaca, The cyanohydrins synthesized are obtained in good chemical yield with excellent enantioselectivities.

  to accelerate cyanohydrin synthesis under neutral conditions with an insoluble cyanide source (KCN) without generating toxic HCN. Under inert atmosphere, the reaction is essentially not operative due to the unfavored equilibrium. The utility of CO2‐mediated selective cyanohydrin synthesis was further showcased by broadening Kiliani–Fischer synthesis under neutral conditions. This protocol offers an

  化学过程的热力学和动力学控制是获得所需产品和状态的关键。当无法获得所需产品时进行更改；可以用另外的试剂，催化剂和/或保护基来操纵反应。在这里，我们报告使用二氧化碳在不溶性氰化物源（KCN）的中性条件下加速氰醇合成，而不会产生有毒的HCN。在惰性气氛下，由于不利的平衡，该反应基本上不起作用。CO 2的效用扩大中性条件下的Kiliani–Fischer合成进一步展示了介导的选择性氰醇合成。通过简单地从烷基和芳基醛，KCN和大气压CO 2开始，该协议可轻松访问各种多元醇，氰醇，直链烷基腈。

  A reaction system, wherein a cyanohydrin is converted into an optically active α-hydroxy acid or α-hydroxyamide via a treatment in a reaction tank (f) with a microorganism, is provided with an automatic cyanohydrin controller (h) comprising a cyano ion detector (a), a regulator (b) and a cyanohydrin supplier (i) and (j) linked thereto. The reaction is performed while automatically controlling the cyanohydrin concentration. Thus cyanohydrin can be supplied under automatic control at a relatively low and constant concentration on the basis of its consumption ratio. The reaction rate of the catalyst can be continuously regarded as the rate-limiting factor. As a result, a decrease in the enzymatic activity during the reaction can be suppressed and an optically active α-hydroxy acid or α-hydroxyamide can be efficiently obtained at a high yield.

  一种反应系统，通过在反应罐（f）中用微生物处理氰醇，将其转化为具有光学活性的 α-羟基酸或α-羟基酰胺，该系统配有氰醇自动控制器（h），该控制器由氰基离子检测器 （a）、调节器（b）以及与之相连的氰醇供应商（i）和（j）组成。反应在自动控制氰醇浓度的同时进行。 因此，氰醇可以在自动控制下，根据其消耗比，以相对较低且恒定的浓度供应。催化剂的反应速率可持续视为限速因素。因此，可抑制反应过程中酶活性的降低，并以高产率有效地获得具有光学活性的 α- 羟基酸或α- 羟基酰胺。
