Resumo
It has been revealed that the copper(II) triflate catalyzed reaction of ethyl-2-diazo-3-oxobutanoate with phenols followed by cyclization of the intermediate enol in the presence of polyphosphoric acid is a simple and efficient method of synthesis of polysubstituted benzofurans. The use of pyrocatechol leads to the corresponding substituted 1,4-benzodioxine-2-carboxylates as major products.
