group for the amino group, are conveniently prepared by reaction of potassium phthalirnide with alkyl halides, in the first step of the Gabriel synthesis." Alternatively, direct N-alkylation of maleimides and phthalimides can be accomplished by the Mitsunobu reaction, using alcohols as the alkyl group donors , I 2 The activating agents in the Mitsunobu protocol are triphenylphosphine and azodicar-
马来酰亚胺衍生物作为生物应用中的底物受到高度关注。由于其迈克尔接受能力,马来酰亚胺基团能够与亲核基团反应,例如。G。生物分子中的硫醇基团。I 因此,含有末端马来酰亚胺功能的底物可以与酶或其他蛋白质的半胱氨酸残基共价偶联?一端带有马来酰亚胺基团而另一端带有可连接官能团的双功能衍生物可用于交联蛋白质?~~马来酰亚胺在Diels-Alder型环加成反应中被广泛用作与多种二烯的亲二烯体:S6在文献中,仅描述了少量合成 N-取代马来酰亚胺的方法。一种常用的方法是将氨基甲酸酐与马来酸酐反应,然后脱水?-9 然而,
