  摘要：

  细胞色素P450酶在许多生物系统中执行一系列选择性氧化生物转化。细菌酶CYP199A4催化4-甲氧基苯甲酸的氧化脱甲基作用。分子的苯甲酸部分在酶的活性位点结合，从而使对位的官能团保持在血红素铁附近。因此，CYP199A4有可能催化与不同的对位取代的苯甲酸底物（例如硫醚和烷基胺）发生交替的单加氧酶反应。CYP199A4对4-甲基-和4-乙基-硫代苯甲酸的氧化导致硫的氧化。通过CYP199A4进行的4-乙基硫代苯甲酸亚硫酸盐氧化和4-乙基苯甲酸的羟基化具有高对映选择性（> 74％对映体过量）。相比之下，CYP199A4在与4-甲基和4-二甲基氨基苯甲酸形成N-氧化物时催化了专有的氧化N-脱甲基化作用。出乎意料的是，由CYP199A4形成的乙酰胺与4-烷基-和二乙基-氨基苯甲酸的周转中的脱烷基反应竞争。用3，4-亚乙二氧基苯甲酸未观察到氧化脱烷基，仅羟基化形成环状半缩醛。解决了酶的四种底物结合形

  and catalytic mono-N-alkylation method of both aromatic and aliphatic amines using nitriles as an alkylating agent with Pd/C or Rh/C as a catalyst is described. This method is particularly attractive to provide an environmentally benign and applicable alkylation method of amines without using toxic and corrosive alkylating agents such as alkyl halides and carbonyl compounds.

  the one-pot hydrogenation of the nitro group and the reductive alkylation of the amines. While aliphatic amines were effectively converted to the corresponding tertiary amines under Pd/C-catalyzed conditions, Rh/C was a highly effective catalyst for the N-monoalkylation of aliphatic primary amines without over-alkylation to the tertiary amines. Furthermore, the combination of the Rh/C-catalyzed N-monoalkylation

  发现腈是在催化氢化条件下用于胺的选择性N-烷基化的高效烷基化试剂。对于芳族伯胺，相应的仲胺是在以下条件下有选择地获得的：钯/ C催化的氢化条件。尽管使用电子贫乏的芳族胺或庞大的腈显示出对还原烷基化反应的较低反应性，但添加NH 4 OAc增强了反应活性，从而以优异的产率获得了芳族仲胺。在相同的反应条件下，芳族硝基化合物代替芳族伯胺可以通过多胺反应直接转化为仲胺，该反应涉及硝基的一锅加氢和胺的还原烷基化。脂族胺在以下条件下有效地转化为相应的叔胺钯/ C催化的条件， 铑/ C是用于脂族伯胺的N-单烷基化而不会过度烷基化成叔胺的高效催化剂。此外，铑/ C催化的脂肪族伯胺的N-单烷基化反应及其他钯所得仲脂族胺的/ C催化烷基化可以选择性地制备具有三个不同烷基的脂族叔胺。根据机理研究，似乎可以合理地得出以下结论：在反应的第一步中，在胺发生亲核攻击之前，腈被还原为醛亚胺。
