Manganese-Mediated Electrochemical Dearomatization of Indoles To Access 2-Azido Spirocyclic Indolines
Kangdong Mo, Xiaocong Zhou, Ju Wu, Yufen Zhao
Abstract
An efficient and environmentally friendly electrochemical protocol for dearomatization of indoles was developed, delivering a series of azido-containing spirocyclic indolines with good functional group tolerance. This dearomatization process is proposed to result from the oxidation of MnII–N3 species, supported by cyclic voltammetry experiments. Moreover, synthetic transformations can provide an alternative approach to a range of functionalized indolines.
