derivatives, can be obtained by different synthetic routes. These compounds can undergo a large variety of reactions, such as Diels–Alder, epoxidation, methanol addition and conjugate addition reactions of different types of nucleophiles, including carbon (cyanide), nitrogen (piperidine) and sulfur (thiols, thioacetate) nucleophiles. The reactivity with electrophilic reagents, such as m-CPBA or methanol
可以通过不同的合成途径获得5-亚甲基乙内酰脲,以及N-单-和N,N-二-保护的衍生物。这些化合物可以进行多种反应,例如不同类型亲核试剂的Diels–Alder反应,环氧化反应,甲醇加成反应和共轭加成反应,包括碳(氰化物),氮(哌啶)和硫(硫醇,硫代乙酸酯)亲核试剂。在酸性介质中,与亲电试剂(例如m- CPBA或甲醇)的反应性以及对路易斯酸促进共轭加成反应的需求表明乙内酰脲是一个较差的吸电子基团。
