The primary hydroxyl groups of d-glucose and 2-acetamido-2-deoxy-d-glucose were selectively esterified by treating the free sugars with activated esters of peptides in the presence of imidazole, thus affording exclusively 6-O-peptidyl-d-glucopyranoses.
通过在咪唑存在下用肽的活化酯处理游离糖来选择性地酯化d-葡萄糖和2-acetamido-2-deoxy-d-葡萄糖的伯羟基,从而仅得到6 - O-肽基-d-吡喃葡萄糖。
