An oxidative coupling strategy involving hypervalent organoiodine-induced
oxidative dearomatization of 4-substituted phenols, Brønsted
acid catalyzed Michael addition with indoles, and aromatization
has been developed. The one-pot reaction provides an efficient access
to the meta-indole-substituted phenol
derivatives.
aromatic substitution - biaryls - cross-coupling
reaction - oxidation - regioselectivity
