The preparation of hydroxy amides from a wide variety of lactones and amines has been achieved at 9 kbar and 30 or 65 °C. The yields of hydroxy amides were moderate to excellent. Some limitations were encountered in the reaction of 6-hexanolide; for example, diethylamine gave only a 15% yield of the corresponding amide at 8 kbar and 60 °C. 4-Pentanolide did react with extremely unreactive amines such
已在 9 kbar 和 30 或 65 °C 下实现了由多种内酯和胺制备羟基酰胺。羟基酰胺的产率中等至极好。6-己内酯的反应遇到了一些限制;例如,二乙胺在 8 kbar 和 60 °C 下仅产生 15% 的相应酰胺收率。4-戊内酯确实与极不活泼的胺如4-硝基苯胺和二苯胺反应,产物是羟基酰胺和3-氨基丁酸的混合物。
