Abstract

A simple and practical two-step procedure for the preparation of 2-unsubstituted 1-benzo[b]furan-3-carboxylic acid methyl esters is described. The procedure uses the copper-catalyzed intramolecular C-O bond formation and provides an efficient route to the title compounds in good to excellent yields.
