  摘要：

  在60％的水溶液中，用溴异氰尿酸单钠盐（BICA-Na）溴化未保护的芳香族氨基酸，例如苯丙氨酸，酪氨酸和甘氨酸。H（2）SO（4）在0摄氏度下以高收率得到单溴化产物的混合物。出乎意料的是，获得了间溴苯甘氨酸作为主要产物，同时伴随有邻位和对位取代的产物，而苯丙氨酸仅给出了邻位和对位取代的产物。2-苯基乙胺或苄胺的溴化显示出与相应氨基酸相似的趋势。

• Synthesis of Unprotected 2-Arylglycines by Transamination of Arylglyoxylic Acids with 2-(2-Chlorophenyl)glycine
  作者：Haruki Inada、Masatoshi Shibuya、Yoshihiko Yamamoto

  日期：2020.9.4

  The transamination of α-keto acids with 2-phenylglycine is an effective methodology for directly synthesizing unprotected α-amino acids. However, the synthesis of 2-arylglycines by transamination is problematic because the corresponding products, 2-arylglycines, transaminate the starting arylglyoxylic acids. Herein, we demonstrate the use of commercially available l-2-(2-chlorophenyl)glycine as the

  用2-苯基甘氨酸对α-酮酸进行氨基转移是直接合成未保护的α-氨基酸的有效方法。但是，通过氨基转移合成2-芳基甘氨酸是有问题的，因为相应的产物2-芳基甘氨酸使起始的芳基乙醛酸发生氨基转移。在此，我们展示了使用可商购获得的升-2-（2-氯苯基）甘氨酸作为在arylglyoxylic酸氨基转移氮源，在不脱离不希望的自转移方法干扰产生相应的2-芳基甘氨酸。
