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.
由可商购的d-异抗坏血酸和l-抗坏血酸制备2-O-甲基-d-赤藓糖,2-O-甲基-1-苏糖,2-脱氧-d-和l-赤藓糖,以及相应的丙酮化物。 。通过1 H和13 C NMR光谱法测定(D 2 O)水溶液中环状(α和β呋喃糖酶)和非环状(醛和水合物)形式的比例。
