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
通过使用NAP醚基团进行永久羟基保护,开发了一种用于合成6''-官能化α-GalCers的通用策略,该策略提供了将各种官能团掺入目标分子(包括炔烃,叠氮化物,硫醇)所需的灵活性不耐Pd催化的氢解以及其他功能(如羧酸和胺)的金属。该策略也适用于其他糖缀合物合成,尤其是那些包含可点击标签和不饱和官能团的糖缀合物。
