Abstract The title 1,3-anhydro sugar was synthesized from methyl α - d -glucopyranoside. The key intermediate for the synthesis was 3- O -acetyl-2-azido-4,6-di- O -benzyl-2-deoxy- α - d -mannopyranosyl chloride ( 11 ) which was transformed into the target compound by ring closure with potassium tert -butoxide.
摘要由甲基α-d-吡喃葡萄糖苷合成了标题1,3-脱水糖。合成的关键中间体是3- O-乙酰基-2-叠氮基4,6-二-O-苄基-2-脱氧-α-d-甘露吡喃糖基氯(11),其通过闭环转化为目标化合物与叔丁醇钾。
