为 functionalized spiro 的一个有效合成过程[indoline-3,4-pyridine ] 作为基础催化剂与 triethylamine 经由 arylamines, acetylenedicarboxylates,靛红和 malononitrile 的四部件的反应被开发。这反应的优点正在使用普通开始的材料,温和反应条件,反应物的宽广范围和运作的简洁。
An efficient synthetic procedure for the functionalized spiro[indoline-3,4'-pyridine] was developed via the four-component reactions of arylamines, acetylenedicarboxylates, isatins and malononitrile with triethylamine as the base catalyst. The advantages of this reaction are using common starting material, mild reaction conditions, broad scope of reactants and operational simplicity.
