  摘要：

  已获得 36 种甲基化四氢萘和四氢蒽的碳 13 化学位移数据。对明确构象的化合物的环碳进行了最小二乘回归分析，以确定两个不同脂肪族位置的甲基取代参数，结果已用于估计构象移动化合物的平衡位置。得出的结论是，1-甲基萘满在室温下以基本相同的构象异构体存在，但 2-甲基衍生物主要由具有赤道甲基的构象支配。将取代基参数与先前为甲基化环己烷确定的参数进行比较。对甲基化学位移的类似分析没有成功，部分原因是饱和环的高度柔性。

  Asymmetric biomimetic transamination is a highly attractive method for synthesis of chemically and biologically important chiral amino acids and chiral amines. Development of chiral pyridoxamines/pyridoxals is the key for the reaction. New axially chiral biaryl pyridoxamines based on H4-naphathene skeleton have been developed. The pyridoxamines display good enantioselectivity and high catalytic activity

  multi-nuclear NMR spectroscopy observed during catalysis. The activation parameters (ΔH≠ = 13.4 ± 0.5 kcal/mol; ΔS≠ = -24.3 ± 1.7 cal/mol·K) were measured using Eyring analysis, implying a highly ordered transition state during the HAA step. The proposed mechanism of rapid iminyl formation, rate-determining HAA, and subsequent radical recombination was corroborated by intramolecular isotope labeling experiments

  Intermolecular C-C bond-forming reactions are underdeveloped transformations in the field of biocatalysis. Here we report a photoenzymatic intermolecular hydroalkylation of olefins catalyzed by flavin-dependent 'ene'-reductases. Radical initiation occurs via photoexcitation of a rare high-order enzyme-templated charge-transfer complex that forms between an alkene, α-chloroamide, and flavin hydroquinone

  分子间CC键形成反应是生物催化领域尚未发展的转化。在这里，我们报道了由黄素依赖性“烯”还原酶催化的烯烃光酶分子间加氢烷基化。自由基引发是通过一种罕见的高阶酶模板电荷转移复合物的光激发而发生的，该复合物在烯烃、α-氯酰胺和黄素氢醌之间形成。这种独特的机制确保只有当两种底物都存在于蛋白质活性位点内时才会发生自由基形成。该活性位点可以控制自由基终止氢原子转移，从而能够合成对映体丰富的γ-立体酰胺。这项工作凸显了光酶催化通过以前未知的电子转移机制实现新的生物催化转化的潜力。
