The N-Troc (2,2,2-trichloroethoxycarbonyl) groups in glucosamine and muramic acid derivatives were removed by treatment with tetrabutylammonium fluoride (TBAF) under mild conditions. The use of Troc protection for the amino group in aminosugars such as glucosamine is increasing the importance for selective and efficient glycosylation, and the cleavage method described here will expand the available
通过在温和的条件下用四丁基氟化铵(TBAF)处理,可去除氨基葡萄糖和山梨酸衍生物中的N-Troc(2,2,2-三氯乙氧基羰基)基团。在氨基糖(例如葡萄糖胺)中对氨基的Troc保护作用的使用对于选择性和有效糖基化的重要性日益增加,此处描述的裂解方法将扩大在许多聚糖制备中使用Troc基的可用机会。该裂解对于不稳定的化合物或在酸性条件,强碱性条件或还原条件下可分解的化合物特别有利。
