Dehydrogenation of A2-imidazolines (416 Z = NR) gives imidazoles, but requires quite high temperatures and a catalyst such as nickel or platinum. Alternatively, hydrogen acceptors such as sulfur or selenium can be used (70AHC( 12)103). A2-Imidazoline derivatives (417) are thermally converted into imidazoles (418) by a retro-Diels-Alder sequence (93JOC3387). [Pg.427]

A2-Imidazolines (416 Z = NH) are cyclic amidines and exhibit the characteristic resonance stabilization and high basicity. A2-Oxazolines (416 Z = O) are cyclic imino ethers, and A2-thiazolines (416 Z = S) are imino thioethers both are consequently easily hydrolyzed by dilute acid. [Pg.429]
