• One-Pot, Regioselective Synthesis of Substituted Arylglycines for Kinetic Resolution by Penicillin G Acylase
  作者：Peter Grundmann、Wolf-Dieter Fessner

  DOI：10.1002/adsc.200800203

  日期：2008.8.4

  phenylacetamide and glyoxylic acid offers an inexpensive route to a large variety of N-phenylacetylated arylglycines that are suited for immediate enzymatic resolution by penicillin G acylase. When performed under mild conditions at 5 °C in acetic acid/HCl, this simple one-pot operation resulted in the formation of single regioisomers only (≥98%). Subsequent kinetic resolution of the amino acid derivatives by penicillin

  用苯乙酰胺和乙醛酸将富电子芳烃的酰胺烷基化为廉价的生产各种N-苯基乙酰化芳基甘氨酸的途径提供了一条廉价途径，这些途径适合通过青霉素G酰基转移酶立即进行酶促拆分。当在5°C的乙酸/ HCl中于温和条件下进行时，这种简单的一锅操作只能形成单一的区域异构体（≥98％）。随后在E值> 100的情况下，发生青霉素G酰基转移酶对氨基酸衍生物的动力学拆分，通常E值> 100，因此可提供具有高对映体纯度的游离（S）-构型芳基甘氨酸。对应的对映体（R底物，可通过相选择萃取工艺轻松分离，可在常规水解过程中提供相应的（R）-对映异构体。此一锅，两步的芳基甘氨酸合成，拆分和后处理程序需要最少的设备，并允许以小规模快速接触非天然α-氨基酸的对映体（S）和（R）对映体-大量生产。
