ChemInform Abstract: A Palladium- and Copper-Catalyzed Synthesis of Dihydro[1,2-b]indenoindole-9-ol and Benzofuro[3,2-b]indolines: Metal-Controlled Intramolecular C—C and C—O Bond-Forming Reactions.
文摘
Starting from the same precursors, indenoindole derivatives are conveniently obtained by palladium-catalyzed tandem -arylation/nucleophilic addition, whereas the copper-catalyzed cascade approach involving a nucleophilic addition/Ullman-type C—O coupling affords benzofuroindolines.
