  • An easy access to halide ion-catalytic α-glycosylation using carbon tetrabromide and triphenylphosphine as multifunctional reagents
    作者:Yuko Shingu、Yoshihiro Nishida、Hirofumi Dohi、Kazukiyo Kobayashi
    DOI:10.1039/b303984f
    日期:——
    The reaction of a 2-O-benzyl-1-hydroxy sugar with CBr4 and Ph3P generates a glycosyl bromide in situ, which is coupled with an acceptor alcohol in the presence of N,N-tetramethylurea to afford an α-glycosyl product virtually quantitatively. In a proposed pathway, the reagent combination plays multiple roles such as the generation of a glycosyl donor, the activation of glycosylation, and the dehydration of the reaction system. These roles allow a simple α-glycosylation to be performed without special attention to dehydration. Various α-glycosyl (D-gluco-, D-galacto- and L-fuco-) products including glycosyl glycerols and cholesterols have been prepared with this method.
    2-O-苄基-1-羟基糖与CBr4和Ph3P反应生成一种即时的糖基溴化物,该溴化物在N,N-四甲基脲存在下与受体醇耦合,几乎定量地得到α-糖基产物。在提出的反应途径中,试剂组合扮演了多个角色,如糖基供体的生成、糖基化的活化以及反应体系的脱水作用。这些角色使得一个简单的α-糖基化反应得以进行,而无需特别关注脱水步骤。利用这种方法已经制备了多种α-糖基(D-葡萄糖、D-半乳糖和L-岩藻糖)产物,包括糖基甘油和胆固醇。
