A copper-catalyzed tunable oxygenative rearrangement reaction of tetrahydrocarbazoles by using H2O and O2 as oxygen source has been developed. Accordingly, highly important yet synthetically difficult cyclopentyl-bearing spiroindolin-2-one and spiroindolin-3-one products were obtained with excellent chemoselectivity and regioselectivity. Inspired from the unique pathway of 1, 2-migration rearrangement
开发了一种以H 2 O和O 2作为氧源的铜催化四氢咔唑可调节氧化重排反应。因此,获得了高度重要但合成困难的带有环戊基的螺吲哚啉-2-酮和螺吲哚啉-3-酮产物,具有优异的化学选择性和区域选择性。受1, 2-迁移重排独特途径的启发,还开发了一种高度可控的吲哚羟基化方法,用于构建C3a-羟基亚胺二氢吲哚。
