The development of an efficient method for the site‐selective substitution of unprotected phenols has long been considered as an attractive but challenging task. Herein, we describe a highly chemo‐ and ortho‐selective substitution reaction of phenols with α‐aryl α‐diazoacetates with commercially available (C6F5)3B as the catalyst. This reaction proceeds under simple and mild conditions with high efficiency
长期以来,人们一直认为开发一种有效的方法来对未保护的酚进行位点选择性取代是一项有吸引力的任务,但具有挑战性。本文中,我们描述了苯酚与α-芳基α-重氮乙酸酯的高度化学和邻位选择性取代反应,并以市售(C 6 F 5)3 B作为催化剂。该反应在简单温和的条件下以高效率进行,它具有广泛的底物范围,并且易于扩大规模。
