Copper-Catalyzed Synthesis of Indolyl Benzo[b]carbazoles and Their Photoluminescence Property

A copper-catalyzed cascade cyclization of dihydroisobenzofurans with indoles for the rapid construction of indoly benzo[ b ]carbazoles has been reported, providing the desired products in moderate to good yields under mild conditions along with a broad substrate scope and good functional group tolerance. The photoluminescence property of these indoly benzo[ b ]carbazoles has also been investigated.
