using the sulfoxide glycosylation reaction to form the glycosidic linkages. In the course of completing the synthesis of ciclamycin 0, we developed new glycosylation conditions that improve the outcome of the sulfoxide reaction. The conditions involve the addition of agents that scavenge phenylsulfenyl triflate, a highly reactive byproduct that forms following activation of anomeric sulfoxides with triflic
我们开发了一种直接有效的合成环霉素 0 的途径,使用亚砜糖基化反应形成糖苷键。在完成环霉素 0 的合成过程中,我们开发了新的糖基化条件,以改善亚砜反应的结果。这些条件包括添加清除苯亚磺酰三氟甲磺酸酯的试剂,三氟甲磺酸苯硫酯是在异头亚砜与三氟甲磺酸酐活化后形成的高反应性副产物。
