henyl-2,3-dihydroisoindolinones via multicomponent one-pot reaction involving 2-iodo-N-phenylbenzamides, terminal alkyne, and substituted indoles in aqueous micellar medium. It involves copper-mediated domino Sonogashira-5-exo-dig-cyclization followed by regioselective nucleophilic addition of indoles, all in one-pot, using CuI as catalyst and 2,2′-(1E,1′E)-(1R,2R)-cyclohexane-1,2-diylbis(azan-1-y
通过涉及2-碘-N-苯基苯甲酰胺的多组分一锅反应,开发了一种环境友好且操作简单的方法来合成3-苄基-3-(吲哚-3-基)-2-苯基-2,3-二氢异吲哚满酮,末端炔烃和胶束介质水溶液中的取代的吲哚。它涉及使用CuI作为催化剂和2,2'-(1 E,1'E)-(1)铜介导的多米诺骨牌Sonogashira-5-exo-dig-环化反应,然后在一个锅中对吲哚进行区域选择性亲核加成。在好氧条件下,以R,2 R)-环己烷-1,2-二基双(氮杂-1-基-1-亚烷基)双(甲基-1-基-1-亚烷基)二酚为配体。
