An efficient and convenient method for the synthesis of oxazole derivatives from enamides has been established via a ruthenium-catalyzed C–O cyclization. This protocol allows for a wide functional group compatibility, broad substrate scope and ease of operation. This catalytic method is also applicable to other 5-membered O-containing and S-containing heterocyclic systems involving thiazole and furan scaffolds, thus this strategy can be broadly applied to organic synthesis and medicinal chemistry.
