A Brønsted acid catalyzed aza-Friedel–Crafts reaction of indolizines with 3-hydroxyisoindolinones has been established, which constructs isoindolinone derivatives bearing a tetrasubstituted stereocenter in good to high yields and enantioselectivities. Notably, this strategy provides a new access to C1-functionalization of indolizines with excellent regioselectivities. Moreover, this intriguing C1-regioselective
建立了布朗斯台德酸催化的氮杂吲嗪与 3-羟基异吲哚啉酮的氮杂-弗里德尔-克来福特反应,该反应构建了具有四取代立构中心的异吲哚啉酮衍生物,具有良好至高的产率和对映选择性。值得注意的是,该策略提供了具有优异区域选择性的中氮茚 C1 功能化的新途径。此外,这种有趣的 C1 区域选择性转变是在热力学控制下诱导的。
