A versatile strategy for the synthesis of 6″-functionalized α-GalCers by using NAP ether group for permanent hydroxyl protection was developed, which provide the flexibility necessary for the incorporation of a wide range of functional groups in target molecules including alkyne, azide, thiol that are intolerant to Pd-catalyzed hydrogenolysis as well as other functionalities like carboxylic acid and amine. This strategy is also adaptable to other glycoconjugate synthesis especially those containing clickable tags and unsaturated functionalities.
开发了一种通用策略,通过使用NAP醚基团进行永久性羟基保护来合成6″-官能化α-半乳糖神经酰胺,该策略为在目标分子中引入广泛的官能团提供了必要的灵活性,这些官能团包括对钯催化氢解不耐受的炔烃、叠氮化物、硫醇以及其他官能团,如羧酸和胺。该策略也适用于其他糖缀合物的合成,特别是那些含有可点击标签和不饱和官能团的糖缀合物。
