描述了醛-D-木糖四乙酸酯 (I) 的改进脱巯基程序。 2. 合成了D-二甲苯酰氯(III)和1-脱氧-L-重氮-ee/oD-山梨糖(IV)的四乙酸酯。后者与乙酸反应导致合成酮-山梨糖五乙酸酯(V)，通过皂化得到D-山梨糖(VI)。 3.得到&e/oL-山梨糖五乙酸酯肟。4．描述了酮-，L-山梨糖五乙酸酯。 5. 1, 8-双重氮-粘基二甲烷四乙酸酯的氢碘酸还原产生粘基二甲烷四乙酸酯(VII)。
An improved demercaptalation procedure for aldehydo-D-xylose tetraacetate (I) is described. 2. The tetraacetates ofD-xylonyl chloride (III) and of 1-desoxy-l-diazo-ée/oD-sorbose (IV) have been synthesized. Reaction of the latter with acetic acid led to the synthesis of keto-dsorbose pentaacetate (V), from which D-sorbose (VI) was obtained on saponification. 3. An oxime of &e/oL-sorbose pentaacetate has been obtained.4. keto-, L-Sorbose pentaacetate is described. 5. Hydriodic acid reduction of 1, 8-bisdiazo-mucyldimethane tetraacetate yielded mucyldi-methane tetraacetate (VII).
