Glycosylation reactions are significant as they provide access to model compounds that are useful for elucidating biochemical pathways. Herein, we describe the development of glycosyl ortho-alkynylbenzoates as novel, bench-top stable, and readily available glycosyl donors. Glycosylation is promoted by inexpensive trimethylsilyl triflate (TMSOTf) in combination with N-iodosuccinimide (NIS) under mild
糖基化反应很重要,因为它们提供了可用于阐明生化途径的模型化合物的途径。在本文中,我们描述了糖基邻炔基苯甲酸酯作为新型,台式稳定且易于获得的糖基供体的发展。廉价的三甲基甲硅烷基三氟甲磺酸酯(TMSOTf)与N-碘代琥珀酰亚胺(NIS)组合可在温和的反应条件下促进糖基化。因此,新型糖基供体是合成糖苷的有前途的试剂。
