catalysts is still largely limited by the limitations of current cross-coupling methodologies. For this reason, despite the importance of sterically demanding catalysts in Bronsted acid catalysis, highly hindered congeners are still unprecedented. Exploiting the aryne addition reaction as key step, we report herein the development of a novel synthetic route to access this unexplored class of catalysts.
3-3'-取代的 BINOL 衍生的手性
磷酸催化剂的合成仍然很大程度上受到当前交叉偶联方法的限制。出于这个原因,尽管在布朗斯台德酸催化中空间要求高的催化剂很重要,但高度受阻的同类物仍然是前所未有的。利用
芳烃加成反应作为关键步骤,我们在此报告了一种新的合成路线的开发,以获取这类未开发的催化剂。
