Disclosed is a process for producing alanylglutamine, which comprises reacting an N-(2-substituted)-propionylglutamine compound represented by the formula (I):
where X represents halogen, alkylsulfonyloxy, or substituted or unsubstituted arylsulfonyloxy, with ammonia at a temperature of 60°C or below.
In accordance with the present invention, highly purified alanylglutamine can be produced in a high yield, without racemization.
本发明公开了一种生产丙氨酰谷氨酰胺的工艺,该工艺包括使式 (I) 所代表的 N-(2-取代)-丙氨酰谷氨酰胺化合物发生反应:
其中 X 代表卤素、烷基磺酰氧基或取代或未取代的芳基磺酰氧基,与氨在 60°C 或以下的温度下反应。
根据本发明,可以高产率生产高纯度的丙氨酰谷氨酰胺,且不会发生外消旋化。
