Treatment of reducing 6-O-tosyl-D-glycopyranoses 1 with 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) afforded the corresponding 1,6-anhydro-ß-D-hexopyranoses 2 in high yields. Reaction was also performed on partly acetylated tosylates of carbohydrates.
使用1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)处理6-O-甲苯磺酰基-D-吡喃葡萄糖1,高产率地获得了相应的1,6-脱水-β-D-己吡喃糖2。这种方法同样适用于处理部分乙酰化的糖类甲苯磺酸酯。
