Abstract

The benzoxazole moiety is an important structural motif in many biologically active natural products and pharmaceutical compounds.[1] Development of efficient methods to construct functionalized benzoxazole scaffolds is thus highly relevant for drug discovery. Traditional methods for the preparation of the benzoxazole framework include condensation reactions of 2-aminophenols with carboxylic acids in the presence of acid or the reaction of 2- ...
