groups was synthesized. The obtained 3aB functioned as a photoactivated Lewis acid catalyst. The photoactivation originates from the deformation of the cage-shaped scaffold driven by intramolecular excimer formations of the pyrenes, allowing the catalytic O-glycosylation using glycosyl fluorides to proceed with a high efficiency.
合成了具有
芘基甲基的笼形
硼酸盐3a B 。得到的3a B 起光活化
路易斯酸催化剂的作用。光活化源于由
芘的分子内准分子形成驱动的笼形支架的变形,从而允许使用糖基
氟化物的催化O-糖基化以高效率进行。
