In addition to ketene dithioacetal monoxides that were specially designed and have been used so far, general alkenyl sulfoxides of moderate reactivity have now become applicable as substrates in the trifluoroacetic anhydride-mediated annulation with pheno

An efficient Au-catalyzed transformation for the synthesis of benzofurans from phenols 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.

Regioselective 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.
