Syntheses of L-threose and D-erythrose analogues modified at position 2

2-O-Methyl-D-erythrose, 2-O-methyl-L-threose, 2-deoxy-D- and L- erythrose, and the corresponding acetonides have been prepared from the commercially available D-isoascorbic and L-ascorbic acids. The proportion of cyclic (α and β furanoses) and acyclic (aldehyde and hydrate) forms was determined in aqueous (D2O) solution by 1H and 13C NMR spectroscopy.
