the anomeric mixture of the analogous 4,6-di-O-benzoyl derivative, having HO-2 free. Compound 3 was subjected to debromination with tributyltin hydride and tributyltin deuteride in the presence of 2,2'-azo-bisisobutyronitrile affording, respectively, the corresponding derivatives of 3-deoxy-D-erythro-2-hexulosonic acid and its 3-deuterio analog. The structure of the products and intermediates was established
2,4,6-三-O-苯甲酰基-2,3-二溴-3-脱氧-D-altrono-1,5-内酯的甲醇解反应生成甲基3-溴-3-脱氧-2,4,6-三甲基-O-苯甲酰基-α-D-ribo-hex-2-ulofuranosonate(3)和类似的4,6-二-O-苯甲酰基衍生物的异头混合物,不含HO-2。在2,2'-偶氮二异丁腈的存在下,用氢化三丁基锡和氘代三丁基锡对化合物3进行脱溴处理,分别得到3-脱氧-D-赤型-2-己磺酸及其相应的3-氘代类似物的相应衍生物。 。产物和中间体的结构通过光谱方法和化学转化来确定。
