Abstract

Abstract A variety of oxazoles can efficiently be prepared, in a single step and in good yield, from primary amides and 1, 2-dihaloalkenes using copper-catalysis. This new method allows the regioselective formation of a range of substituted oxazoles. The required 1, 2- dihaloalkenes can prepared by simple treatment of alkynes with elemental bromine or iodine.
