A Mild Cu(I)-Catalyzed Oxidative Aromatization of Indolines to Indoles
摘要:
A novel method for the oxidation of indolines to indoles is described. The method uses a Cu(I) catalyst and an organic percarbonate as the stoichiometric oxidant. The procedure was successfully applied at 0.5 kg scale in the production of a key intermediate in the synthesis of Elbasvir, which is a novel therapy for the treatment of hepatitis C virus infection.

in the one‐pot, multicomponent assembly of substituted indoles from ortho‐chlorohaloarenes, alkyl ketones (including acetone), and primary amines is reported. The described protocols offer improved substrate scope in all three reaction components, under more mild conditions and without the need for an additional drying agent. Also reported are the first examples of such multicomponent reactions where

aromaticity transfer coupling reaction between phenols and pyrrolidines or indolines to generate the corresponding N-cyclohexyl pyrroles or indoles. In this transformation, the aromaticity of phenols is formally passed on to the pyrrolidine or indoline units. Substituted phenols thus can serve as latent cyclohexyl equivalents for the fast construction of various N-cyclohexyl pyrroles and indoles.
