A highly efficient method for the synthesis of oxazole derivatives from simple amides and ketones proceeds through a C-N bond formation followed by a C-O bond formation closing the ring. Because of the simple and readily available starting materials, easy operation, and high bioactivity of oxazoles, this strategy can be broadly applied to medicinal chemistry.
