A copper-mediated synthesis of 2,3-disubstituted benzofurans with the assistance of an 8-aminoquinolyl auxiliary is described from readily available benzamides and benzoylacetonitriles. In this reaction, the C?C bond is successfully constructed via C?H ac

Copper-catalyzed cascade synthesis of 2-aryl-3-cyanobenzofurans from o-hydroxybenzaldehydes and arylacetonitriles in the presence of copper acetate and sodium methoxide is reported. The synthesized 2-aryl-3-cyanobenzofurans emit bright blue under UV light with a quantum yield up to 88.9%. (Chemical Equation Presented).

A novel approach was developed for the synthesis of 2-substituted-3- functionalized benzofurans, using an intramolecular Heck reaction which was further applied in the first enantioselective total synthesis of Daphnodorin B.
Synthesis of (Z)-3-aryloxy-acrylonitriles, (E)-3-aryloxy-acrylonitriles and 3-cyanobenzofurans through the sequential reactions of phenols with propiolonitriles

A Na2CO3-promoted addition of phenols to propiolonitriles generated (Z)-3-aryloxy-acrylonitriles in nearly quantitative yields with exclusively Z-isomers, and a DABCO-promoted addition reaction of phenols with propiolonitriles afforded mainly (E)-3-aryloxy-acrylonitriles with high yields. The obtained (E)-3-aryloxy-acrylonitriles underwent intramolecular cyclization to give 3-cyanobenzofurans in good yields through palladium-catalyzed direct C-H bond functionalization.
