• A novel way to chiral 2-oxazolidinones: selenium-catalyzed cyclocarbonylation of 2-aminoethanols
  作者：Peng Li、Xiaohua Yuan、Shudong Wang、Shiwei Lu

  日期：2007.12

  Selenium-catalyzed cyclocarbonylation of 2-aminoethanols with CO under atmospheric pressure at 30 °C afforded 2-oxazolidinones in excellent yields without any other co-catalyst. The method was then applied to the syntheses of chiral 2-oxazolidinones and no racemization was detected.

  Amino acids are routinely derivatized using carbon-containing groups prior to gas chromatography continuous-flow isotope ratio mass spectrometry (GCC-IRMS). Derivative C contaminates analyte C because the entire derivatized compound is combusted to CO2. Correction procedures are required to extract the analyte isotope ratio. We present a method for reduction of six nonpolar amino acids to their corresponding

  在气相色谱法连续流同位素比质谱法（GCC-IRMS）之前，通常使用含碳基团对氨基酸进行常规衍生化。衍生化合物C污染了分析物C，因为整个衍生化合物都燃烧成二氧化碳。需要校正程序来提取分析物的同位素比。我们提出了一种方法，用于将六个非极性氨基酸还原为其相应的氨基醇，展示了一种从所得强氢键分析物产生可接受峰形的气相色谱策略，并对氨基酸及其相应的氨基醇进行了同位素分析以评估任何可能的同位素分级分离。使用NaBH4在THF中以I2作为亲电试剂还原丙氨酸，缬氨酸，亮氨酸，异亮氨酸，蛋氨酸或苯丙氨酸。用2 g分析物进行反应，以通过常规元素分析-IRMS进行同位素分析。通过IR光谱，熔点和GC评估，所有反应都是定量的。从反应混合物中回收率为60-84％。使用厚的固定相（5微米）毛细管色谱柱可实现六种氨基醇混合物的GC分离，从而避免由于氢键合到熔融石英毛细管壁上而造成拖尾。GCC-IRMS测定的氨基醇的重现性平均值为SD（613C）=
