This study confirms that 2,3,4-tri-O-acetyl-1,6-anhydro-beta-D-mannopyranose is an artifact produced during carbohydrate analysis. A new synthesis of 2,3,5-tri-O-acetyl-1,6-anhydro-beta-D-mannofuranose is also described, and a novel dimer, 1,6':6,1'-dianhydro-2,3:2',3'-di-O-isopropylidene-5,5'-di-O-(1-methox yethyl)-di - alpha-D-mannofuranose, has been isolated. The structure of the dimer is confirmed by X-ray analysis of a derivative, 1,6':6,1'-dianhydro-2,3:2',3'-di-O-isopropylidene-di-alpha-D-mannofur anose.
本研究证实，2,3,4-三-O-乙酰基-1,6-脱水-β-D-甘露吡喃糖是碳水化合物分析过程中产生的一种假象。还描述了2,3,5-三-O-乙酰基-1,6-脱水-β-D-甘露呋喃糖的一种新合成方法，并且分离出了一种新型二聚体，即1,6':6,1'-二脱水-2,3:2',3'-二-O-异亚丙基-5,5'-二-O-(1-甲氧基乙基)-二-α-D-甘露呋喃糖。通过对衍生物1,6':6,1'-二脱水-2,3:2',3'-二-O-异亚丙基-二-α-D-甘露呋喃糖的X射线分析确定了二聚体的结构。
