Heterogeneously Catalyzed Domino Synthesis of 3-Indolylquinones Involving Direct Oxidative C-C Coupling of Hydroquinones and Indoles.

Introduction 3-Indolylquinones are core structures of highly significant biologically active natural products called “asterriquinones”, which are found in fungal species like Aspergillus terreus , Chaetomium sp., and Pseudomassaria sp. 1 − 5 Asterriquinones are emerging as potential pharmacophores due to their wide range of biological activities, including inhibition of
