Acetolysis of 1,6-anhydro sugars can be achieved by treatment with acetic anhydride and triethylsilyl trifluoromethanesulphonate at 0 °C for 5–15 minutes, under which conditions a wide variety of protecting groups are unaffected, and even the trisulphonate is cleaved, albeit in six hours.
1,6-酸酐糖在0℃下与

三氟甲磺酸反应5-15分钟即可发生乙酰化分解。在这些条件下,多种保护基都不受影响,即使是三
磺酸酯也能被裂解,尽管需要6小时。
