  carboxylic acids were transformed into their trimethylsilyl esters with HMDS in a practically completely solvent-free process, while a catalytic amount of iodine was required in some cases. The process has several advantages over the known methods: untreated reactants, air atmosphere, mild and neutral conditions, no evolution of hydrogen halide, no need of an additional base, low amount of waste, completely

  在几乎完全无溶剂的过程中，使用HMDS将多种结构不同的羧酸转化为三甲基甲硅烷基酯，而在某些情况下则需要催化量的碘。与已知方法相比，该方法具有多个优点：未处理的反应物，空气气氛，温和和中性条件，不产生卤化氢，不需要额外的碱，废物量少，完全无需色谱法，能源消耗低以及可操作简单。

  sources. An atom-efficient biocatalytic oxidative cascade was developed for the conversion of saturated fatty acids to α-ketoacids. Employment of P450 monooxygenase in the peroxygenase mode for regioselective α-hydroxylation of fatty acids combined with enantioselective oxidation by α-hydroxyacid oxidase(s) resulted in internal recycling of the oxidant H2 O2 , thus minimizing degradation of ketoacid product

  生物基化学品的功能化对于实现天然碳源的增值至关重要。开发了一种原子效率生物催化氧化级联，用于将饱和脂肪酸转化为 α-酮酸。在过氧合酶模式下使用 P450 单加氧酶对脂肪酸进行区域选择性 α-羟基化，并结合 α-羟基酸氧化酶的对映选择性氧化，导致氧化剂 H2 O2 的内部循环，从而最大限度地减少酮酸产物的降解并最大限度地延长生物催化剂的寿命。依赖 O2 的级联依赖于催化量的 H2 O2，并释放水作为唯一的副产品。在温和条件下，在水性缓冲液中，通过同时的一锅两步级联将辛酸转化为 2-氧代辛酸，转化率高达 >99%，且不会积累羟基酸中间体。通过放大，可以以 91% 的产率分离最终产物，并且级联适用于各种链长（C6:0 至 C10:0）的脂肪酸。
• Identification of Products Containing −COOH, −OH, and −CO in Atmospheric Oxidation of Hydrocarbons

  Atmospheric oxidation of hydrocarbons by hydroxyl radicals and ozone leads to products containing -COOH, -OH, and -C=O functional groups. The high polarity of such compounds precludes direct GC-MS analysis. In addition, many such compounds often exist in a single sample at trace levels. An analytical method has been developed to identify compounds containing one or more functional groups of carbonyl, carboxy, and hydroxy in atmospheric samples. In the method, -C=O groups are derivatized using 0-(2,3,4,5,6-pentafluorobenzyl) hydroxy amine (PFBHA), and -COOH and -OH groups are derivatized using a silylation reagent N,O-bis(trimethylsilyl)trifluoro-acetamide (BSTFA). The derivatives are easily resolved by a GC column. The chemical ionization mass spectra of these derivatives exhibit several pseudomolecular ions, allowing unambiguous determination of molecular weights. Functional group identification is accomplished by monitoring the ions in the electron ionization mass spectra that are characteristic of each functional group derivative: m/z 181 for carbonyl and m/z 73 and 75 for carboxyl and hydroxy groups. The method is used to identify products in laboratory studies of ozone oxidation of alpha-pinene and Delta(3)-carene. Among products from ozone oxidation of alpha-pinene, we have detected pinonaldehyde, norpinonaldehyde , pinonic acid, norpinonic acid, C-10 hydroxy dicarbonyls, pinic acid, 2,2-dimethyl-3-(formylmethyl)-cyclobutane-formic acid, and a product that has a molecular weight of 156 and contains a C=O and a COOH/OH group. The latter two products have not been reported previously. Delta(3)-carene is structurally analogous to alpha-pinene in that both have an internal unsaturated bond where ozone oxidation takes place. We have also identified the corresponding analogous products, of which all but caronaldehyde are reported for the first time.
