Bisphenyl, Bisheteroaryl, indolylaryl and indolylcycloalkyl maleimides are prepared in one step and 67–99% yield by condensation of glyoxylate esters with acetamides using a 1.0 M solution of potassium tert-butoxide in THF. The mechanism of the reaction is discussed.
使用1.0 M叔丁醇钾的THF溶液,通过乙醛酸酯与乙酰胺的缩合,可一步制备联苯,二异芳基,吲哚基芳基和吲哚基环烷基马来酰亚胺,收率67-99%。讨论了反应机理。
