The reaction of chloroacetamide with 2 equiv of γ-aminobutyric acid potassium salts provides a convenient method for the synthesis of substituted 4-[(2-amino-2-oxoethyl)amino]butanoic acids. Alkylation products of 2-aminoacetic and 3-aminopropanoic acid with chloroacetamide were isolated. Thermal cyclization of substituted 4-[(2-amino-2-oxoethyl)amino]butanoic acids afforded 2-(2-oxopyrrolidin-1-yl)acetamides
氯乙酰胺与2当量的γ-氨基丁酸钾盐的反应为合成取代的4-[((2-氨基-2-氧代乙基)氨基]丁酸提供了一种方便的方法。分离出2-氨基乙酸和3-氨基丙酸与氯乙酰胺的烷基化产物。取代的4-[((2-氨基-2-氧代乙基)氨基]丁酸的热环化得到2-(2-氧代吡咯烷基-1-基)乙酰胺。
