Abstract

Under the participation of cheap and readily available CuCl₂, a visible light-induced tandem C(sp³)-H oxidation, C(sp³)-O cleavage and Friedel−Crafts alkylation of indoles and aliphatic ethers in the absence of ligand and oxidants is developed, affording synthetically useful 3,3′-bisindolylmethane derivatives in moderate to good yields. This transformation exhibits broad substrate scope and good functional group compatibility.

期刊介绍： Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry. Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters. Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
