Glycosidation with stable alkyl glycosyl donors using a catalytic amount of gold salts is promising. Herein, 1-ethynylcyclohexanyl glycosides are identified as novel donors at room temperature and mechanistic investigation showed that the leaving group simply extrudes out.
使用少量
金盐催化,以稳定的烷基糖供体进行糖基化反应具有良好的应用前景。在此,我们发现
1-乙炔基环己烷糖苷在室温下可以作为新型供体,并且机理研究表明离去基团直接脱离。
