(C6F5)3B Catalyzed Chemoselective and ortho-Selective Substitution of Phenols with α-Aryl α-Diazoesters

The development of an efficient method for the site‐selective substitution of unprotected phenols has long been considered as an attractive but challenging task.

Description
Summary: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, it features a wide substrate scope and can be easily scaled up. Herausforderung gemeistert: Kommerziell erhältliches (C6F5)3B als Katalysator ermöglicht die chemo‐ und ortho‐selektive Substitution von Phenolen mit α‐Aryl‐α‐diazoacetaten. Die Reaktion läuft unter milden Bedingungen mit hoher Effizienz ab, zeichnet sich durch eine große Substratbreite aus und kann leicht skaliert werden.
