The reaction between N-benzylpropargylamines and acid chlorides at elevated temperatures provides efficient, direct access to a variety of di- and tri-substituted oxazoles. The versatility of this reaction is explored and 21 examples are demonstrated. The usefulness of the methodology is showcased through the short and efficient formal syntheses of medicinally relevant drugs aleglitazar and romazarit
