Derivatives of 1-(2-(2-dimethylaminoethyl)benzyliden)isoindolin-3-one underwent deamination on reaction with epoxides under mild conditions. Amide group of the substrate reacted slower with epoxide than the dimethylamino grouping whilst the alkanolamide was formed with a great excess of the epoxide only. Of epoxides used in this reaction 1,2-epoxy-3-phenoxypropane, 3-decyloxypropane and 3-chloro-1,2-epoxypropane, the first was found to react most rapidly.
1-(2-(2-二甲基氨基乙基)苯甲亚甲基)异吲哚啉-3-酮的衍生物在温和条件下与环氧化物反应时发生去胺反应。底物的酰胺基团与环氧化物的反应速度较二甲基氨基基团慢,而仅在大量环氧化物存在时,才形成了烷基酰胺。在本反应中使用的环氧化物包括1,2-环氧基-3-苯氧基丙烷、3-癸氧基丙烷和3-氯-1,2-环氧基丙烷,其中第一种反应速度最快。
