A green and efficient method has been accomplished for the synthesis of α-hydroxyphosphonates using silica-supported tungstic acid (STA) as a heterogeneous catalyst under solvent-free conditions at ambient temperature. The compounds obtained were characte

Dimethyl α-hydroxyalkyl-, α-hydroxybenzyl-, α-hydroxyfurfuryl-, and α-hydroxy-α-thienylmethyl-phosphonates have been prepared in good yield by the alumina-catalyzed reaction of dimethyl phosphite with the corresponding alkanals, aryl aldehydes (or aryl methyl ketones), furfuraldehyde, and 2- or 3-thiophenecarboxaldehyde, respectively, thus confirming the general utility of this synthetic procedure. The 1H and 13C nmr spectra of the products exhibit characteristic chemical shift non-equivalence of the diastereotopic methyl ester groups, for which a tentative order of non-equivalence is reported and discussed.
