应用异头o -烷基化/芳基化反应合成了2-脱氧β-糖苷。在二氧六烷中用钠处理乳醇,然后加入亲电试剂,形成了高收率和高选择性的2-脱氧β-糖苷。这里观察到的高β选择性表明,在动力学控制下,缩醛的立体选择性形成具有强大的立体电子效应。
Anomeric O-alkylation/arylation is applied to the synthesis of 2-deoxy-β-glycosides. Treatment of lactols with NaH in dioxane followed by the addition of electrophiles leads to the formation of 2-deoxy-β-glycosides in high yield and high selectivity. The high β-selectivity observed here demonstrates a powerful stereoelectronic effect for the stereoselective formation of acetals under kinetic control.
