For the first time, an aza-Heck cyclization that allows the preparation of indoline scaffolds is described. Using N-hydroxy anilines as electrophiles, which can be easily accessed from the corresponding nitroarenes, this method provides indolines bearing pendant functionality and complex ring topologies. Synthesis of challenging indolines, such as those bearing fully substituted carbon atoms at C2
首次描述了允许制备吲哚啉支架的氮杂-Heck环化反应。使用N-羟基苯胺作为亲电子试剂(可以轻松地从相应的硝基芳烃获得),该方法可提供带有侧链功能和复杂环拓扑结构的二氢吲哚。使用这种方法也可以合成具有挑战性的二氢吲哚,例如那些在C2上带有完全取代的碳原子的二氢吲哚。
