Abstract
The reactivity of 2-trichloromethylbenzoxazoles toward various nucleophiles, under metal-free or iron-catalyzed conditions, for the synthesis of substituted benzoxazoles is described. These methods allow for selective substitution at either the 2- or 2'-position of the benzoxazoles using the same starting materials/reagents. This approach allows for the controlled synthesis of a variety of key derivatives from a single 2-trichloromethylbenzoxazole starting material.
