• Substrate Evaluation of<i>Rhodococcus erythropolis</i>SET1, a Nitrile Hydrolysing Bacterium, Demonstrating Dual Activity Strongly Dependent on Nitrile Sub-Structure

  Rhodococcus erythropolis SET1, a novel nitrile hydrolysing bacterial isolate, has been undertaken with 34 nitriles, 33 chiral and 1 prochiral. These substrates consist primarily of β-hydroxy nitriles with varying alkyl and aryl groups at the β position and containing in several compounds different substituents α to the nitrile. In the case of β-hydroxy nitriles without substitution at the α position

  红球菌 SET1 是一种新型腈水解细菌分离株，已使用 34 种腈、33 种手性和 1 种前手性进行了评估。这些底物主要由 β-羟基腈组成，在 β 位具有不同的烷基和芳基，并且在几种化合物中含有与腈不同的 α 取代基。在 α 位没有取代的 β-羟基腈的情况下，由于分离物的腈水解酶活性，酸是获得的主要产物，以及生物转化后回收的腈。出乎意料的是，当 β-羟基腈在该位置具有乙烯基时，发现酰胺是主要的水解产物。为了进一步探索这种行为，评估了在 α 位置包含吸电子基团的其他相关底物，在 SET1 存在下的生物转化过程中也观察到了酰胺。因此，这种新的分离物也证明了对似乎是底物依赖性的腈类的 NHase 活性。

  Halohydrin dehalogenases (HheA, HheB and HheC) were found to efficiently catalyse a carbon-carbon bond forming reaction between terminal aliphatic epoxides and cyanide, yielding β-hydroxy nitriles. With all three enzymes nucleophilic ring opening of epoxides proceeds with high regioselectivity to the β-carbon atom. Activity, enantioselectivity and enantiopreference depend on the type of enzyme and

  发现卤代醇脱卤素酶（HheA，HheB和HheC）可有效催化末端脂肪族环氧化物与氰化物之间的碳-碳键形成反应，生成β-羟基腈。通过所有这三种酶，环氧化物的亲核开环以对β-碳原子的高区域选择性进行。活性，对映选择性和对映选择性取决于酶的类型和底物结构。发现HheC在测试的酶中具有最高的选择性。对单取代环氧化物的对映选择性从中等到高（E = 5–106）变化，而2,2-二取代环氧化物的拆分以非常高的对映选择性（E= 141和200）。结果表明，卤代醇脱卤酶可能成为从外消旋环氧化物容易地制备对映纯β-羟基腈的有吸引力的催化剂。
• Thiacrown Ether Technology in Lipase-Catalyzed Reaction:  Scope and Limitation for Preparing Optically Active 3-Hydroxyalkanenitriles and Application to Insect Pheromone Synthesis

  Both reaction rate and enantioselectivity in Pseudomonas cepacia lipase (PCL)-catalyzed hydrolysis of 3-hydroxyalkanenitrile acetates were significantly changed by the addition of catalytic amounts of thiacrown ether (1,4,8,11-tetrathiacyclotetradecane). Although the-reaction rate of various nitriles was accelerated, the enantioselectivity greatly depended on the nature of the substrate. Among 10 substrates tested, thiacrown ether offered highest enantioselectivity in PCL-catalyzed hydrolysis of 1-(cyanomethyl)propyl acetate. Forty or more times this crown ether, molarity based on the enzyme, was required to attain an acceptably high reaction rate and enantioselectivity. Applying this technology, we succeeded in synthesizing the optically pure attractant pheromone of ant Myrmica scabrinodis (A), (R)-3-octanol and its antipode of (S)-isomer in good overall yields.
