[reaction: see text] An efficient method for the preparation of 3-aminofuran-2-carboxylate esters has been developed. This method is based on the reaction of an alpha-cyanoketone with ethyl glyoxylate under Mitsunobu conditions to produce a vinylether in good yield. Subsequent treatment of the vinylether with sodium hydride afforded the 3-aminofuran. It was also found that a one-pot procedure using
