Palladium-catalyzed intramolecular cross-coupling reactions between aryl iodides and allyl moieties were successfully demonstrated in the presence of palladium catalyst, tri-o-tolylphosphine, a tertiary amine, and water. Several kinds of trans-2,4-disubstituted 1,2,3,4-tetrahydroquinolines were synthesized in 73-88% yields with excellent diastereoselectivities. This method was further applied to a
在钯催化剂、三邻甲苯基膦、叔胺和水的存在下,成功证明了钯催化的芳基碘化物和烯丙基部分之间的分子内交叉偶联反应。几种反式-2,4-二取代的 1,2,3,4-四氢喹啉以 73-88% 的产率合成,具有优异的非对映选择性。该方法进一步应用于多种底物,通过微波辅助条件以良好的产率形成五元、六元和七元碳和杂环,无论含环原子如何。
