stereocontrolled 1,2-trans-β-glycosidation reaction with or without neighbouring group participation has been developed by using benzyl- or benzoyl-protected glycopyranosyl N,N,N',N'-tetramethylphosphoroamidates as shelf-stable glycosyl donors in the presence of trimethylsilyl trifluoromethanesulfonate or boron trifluoride etherate. Several notable features of the present method not observed with the diphenyl
通过使用苄基或苯甲酰基保护的吡喃葡萄糖基N,N,N',N'-四甲基磷酰胺基酸酯作为在货架上稳定的糖基供体,已经开发了具有或不具有邻近基团参与的高度立体控制的1,2-反式-β-糖苷化反应。存在三甲基甲硅烷基三氟甲磺酸盐或三氟化硼醚化物。还描述了用磷酸二苯酯法未观察到的本方法的几个显着特征。
