Addition of diethyl- and diisopropyl hydrogen phosphites to isomeric (methoxycarbonyl)-2- and 3-furaldehydes in the presence of sodium ethylate or potassium fluoride led to the formation of the corresponding hydroxyphosphonates. When treated with DMSO-acetic anhydride mixture at room temperature these compounds were selectively oxidized to the corresponding furoyl phosphonates. 2-Methoxycarbonyl-3-
