An efficient Au-catalyzed transformation for the synthesis of benzofuransfromphenols and alkynes using molecular oxygen has been developed. The reaction proceeds smoothly with commercially available, eco-friendly oxidant and affords the products in moderate to good yields. This reaction is a facile approach for the formation of C − C and C–O bonds.

synthesis of polysubstituted benzofurans using a copper catalyst and molecular oxygen from phenols and alkynes in a one-pot procedure has been reported. The transformation consists of a sequential nucleophilic addition of phenols to alkynes and oxidative cyclization. A wide variety of phenols and alkynes can be used in the same manner.

The directarylation of benzo[b]furan, benzo[b]thiophene, and indole has been studied by using aromatic bromides as the aryl source. The protocol employing common reagents and a Pd catalyst has led to the regioselective arylation of these heterocycles at the 2-position. A range of functional groups were tolerated, providing quick access to a variety of arylated benzo-fusedheterocycles that would be
