Described herein is the first example of an organocatalytic approach for acylanion addition to the anomeric carbon of 2-nitroglucal using an N-heterocyclic carbene catalyst. Control over the reaction conditions gives β-selective and nitro-eliminated C-glycosides, providing opportunities to produce new classes of C-glycoside.
在此描述的是使用N-杂环卡宾催化剂将酰基丙氨酸加成到2-硝基葡萄糖醛的异头碳中的有机催化方法的第一个例子。控制反应条件使β选择性和硝基消除Ç -glycosides,提供机会,以产生新的类Ç糖苷。
