containing a cycloalkenyl moiety with arylhalides were used in a palladium-catalyzedreaction to give different kinds of rare, fused isoindolinone heterocyclic compounds through highly regioselective C-C coupling/C-H functionalization in a one-step domino reaction. Different dienes and arylhalides were shown to be very active in this reaction. Substituents on the arylhalides were ethoxycarbonyl, methoxycarbonyl
在钯催化的反应中使用含有环烯基部分和芳基卤化物的失活二烯,在一步多米诺反应中通过高度区域选择性的 CC 偶联/CH 官能化得到不同种类的稀有稠合异吲哚啉酮杂环化合物。不同的二烯和芳基卤化物在该反应中表现出非常活跃。芳基卤化物上的取代基是乙氧基羰基、甲氧基羰基、磺酰基、甲酰基、酮基、氰基、乙酰基和萘。当 1-碘苯或芳基卤化物用在保护基上具有烯丙基部分的底物处理时,CH 官能化和烯丙基异构化同时发生。由于这些稠合杂环的合成和药用重要性,该过程的通用性使得该反应具有很高的价值。
