Triflic anhydride mediated synthesis of imidazo[1,5-a]azines

Imidazo[1,5-a]azines are synthesized in moderate to excellent yields using a mild cyclodehydration/aromatization reaction triggered by the use of triflic anhydride (Tf2O) and 2-methoxypyridine (2-MeOPyr). Various substitution patterns and functional groups were found to be compatible under the optimized conditions. In addition, a 5-bromo-3-aryl derivative was also shown to be active in a Sonogashira cross-coupling and direct arylation reactions. A tertiary amide was compatible as a substrate leading to the synthesis of an imidazo[1,5-a]pyridinium triflate.

Vinyl Azides in Heterocyclic Synthesis. Part 3. Isolation of Azirine Trimers (1,3,8-Triazatricyclo3,5>non-7-enes) and Intramolecular Interception of Nitrile Ylides by Neighbouring ?-Bonds or Nucleophiles

Photolysis of azidocinnamates (1a-e) at 300 nm in light petroleum gives exclusively the triazatricyclononenes (7a-e) in a highly stereospecific trimerisation of the corresponding azirine (2).A mechanism is proposed involving the sequence: azide (1) azirine (2) nitrile ylide (8) dimer (9) azomethine ylide (10) trimer (7) (Scheme 2).This mechanism not only rationalises the formation of the trimers (7), rather than dimers or oligomers, but also their stereochemistry.Further evidence for it is provided by photolyses of the azidocinnamates (1f-h) which give the 'dimer' (13), the cyclopropaisoquinoline (16), and the imidazopyridine (20), respectively; these three products result from intramolecular interception of the azomethine ylide or nitrile ylide intermediates.

Photolysis of the azidocinnamates (1) gives trimers of the azirines (2); X-ray crystallographic analysis establishes the triazatricyclononene structure (6) for these trimers.
