    • A synthesis method of alanyl-glutamine includes the steps of: The N-terminal protected alanine reacts with triphenylphosphine and hexachloroethane in organic solvent to form active ester, the active ester reacts with glutamine in a solution mixture containing organic solvent and aqueous solution of inorganic base, the resultant mixture is acidified with inorganic acid, and then the N-terminal protecting group is removed. In this method, the raw materials are cheap, the synthesis technique is simple, no disposals of separation and purification are needed, the product is easy to be separated and purified, the toxicities of all the reagents used in the course of production are minimal, it is advantageous to environment protection.
    • 丙氨酰 - 谷氨酰胺的合成方法包括以下步骤:N-末端保护的丙氨酸与三苯基膦和六氯乙烷在有机溶剂中反应形成活性酯,活性酯与含有机溶剂和无机碱水溶液的溶液中的谷氨酰胺反应 ,将所得混合物用无机酸酸化,然后除去N-末端保护基。 在这种方法中,原料便宜,合成技术简单,不需要分离纯化处理,易于分离和纯化,生产过程中使用的所有试剂的毒性小, 有利于环境保护。
