Strong as an Ox: 2‐Thiazoles and 2‐oxazoles are formed by oxidation of 2‐thiazolines and 2‐oxazolines without requiring substituents at the C4 and C5 positions. DDQ plays an important role as the oxidant in this transformation and metal is unnecessary. This general procedure shows good functional group tolerance and provides a wide variety of 2‐thiazoles and 2‐oxazoles in moderate to excellent yields
