The 1,2-double bond in acetylated glycals has been fluorinated with XeF2 in the presence of BF3 to give 1,2-deoxy-1,2-difluorosaccharides. A mechanism for this reaction has been proposed. This method represents an improvement in the synthesis of 2-deoxy-2-fluorosaccharides.
在BF 3的存在下,已用XeF 2
氟化了乙酰化
缩醛中的1,2-双键,得到1,2-脱氧-1,2-二
氟糖。已经提出了该反应的机制。该方法代表了2-脱氧-2-
氟糖合成的一种改进。
