The copper-catalyzed reaction involves the formation of two C—C bonds and one C—O bond through the cleavage of three C—H bonds in a single operation. The method has an excellent functional group tolerance, and features a broad substrate scope, affording a variety of functionalized chromenes in good yields.展开更多
