  Phosphine-Catalyzed Heine Reaction

  摘要：

  Aziridines are important synthetic Intermediates which readily undergo ring-opening reactions. It is demonstrated that electron-rich phosphines are efficient catalysts for the regioselective rearrangement of N-acylaziridines to oxazolines. The reactions occur in excellent yield under neutral conditions. Evidence is provided for an addition/elimination mechanism by generation of a phosphonium intermediate. Similar intermediates may be useful for the development of alternate aziridine ring-opening processes and stereoselective synthesis with enantiopure phosphines.

  扩大对映选择性卤代醇脱卤酶的范围 – B 组

  摘要：

  卤代醇脱卤酶(HHDHs)具有通过环氧化物的开环反应将诸如N 3、CN、NO 2等官能团引入分子中的非天然活性。HHDH 的对映选择性取决于底物，对于合成应用而言并不总是足够高。由于在相对有限数量的底物上的性能观察到的低对映选择性，HHDH 的 B 组过去一直被忽视。广泛筛选来自分枝杆菌的 HheB2 底物。来自棒状杆菌属的 GP1 和 HheB 。进行了 N-1074。发现了几个高度对映选择性的反应（E>200)，与 HheB2 相比，HheB 对更大的底物面板显示出更高的对映选择性和活性。酶 HheB 和 HheB2 高度同源；它们仅相差 4 个残基。通过使用定点诱变，发现与 HheB2 相比，残基 120 和 125 是 HheB 对映选择性更高的原因。计算分析支持实验并提供证据表明 HheB 酶内反应的动力学和热力学参数对于确定观察到的对映选择性至关重要。如本工作所示，由于显着的活性和对映选择性，B

  Halohydrin dehalogenase from Arthrobacter sp. AD2 catalysed azidolysis of epoxides with high regioselectivity and low to moderate (S)-enantioselectivity (E = 1-16). Mutation of the asparagine 178 to alanine (N178A) showed increased enantioselectivity towards styrene oxide derivatives and glycidyl ethers. Conversion of aromatic epoxides was catalysed by HheA-N178A with complete enantioselectivity, however the regioselectivity was reduced. As a result of the enzyme-catalysed reaction, enantiomerically pure (S)-beta-azido alcohols and (R)-alpha-azido alcohols (ee >= 99%) were obtained. (C) 2016 Published by Elsevier Ltd.
