The transformation of cyclic anhydrides to their corresponding imides involves a mild three-step sequence: (1) reaction with a primary amine, (2) conversion of the intermediate monoamide to an N-hydroxysuccinimidyl ester using N,N′-disuccinimidyl oxalate (DSO), and (3) cyclization by heating the NHS ester in trichloroethylene in the presence of 4-(dimethylamino)pyridine.
环状酸酐向其相应的酰亚胺的转化涉及温和的三个步骤:(1)与伯胺反应,(2)使用N,N'-二琥珀酰亚胺草酸酯(DSO)将中间体单酰胺转化为N-羟基琥珀酰亚胺酯),和(3)在4-氯代二甲基氨基吡啶存在下,在三氯乙烯中加热NHS酯来环化。
