Flash vacuum pyrolysis of arylmethylazides 7a-d gave 2,4-diazapentadienes 5a-d in high yield (76-92%). The thermal cyclization of 5a-d gave cis-imidazolines 1a-d, further heating or Swern oxidation of 1a-d gave dehydrogenated products, imidazoles 2a-d.

Microwave irradiation of a mixture of aromatic aldehydes and hexamethyldisilazane in the presence of a solid catalyst such as alumina afforded methanediamines which were efficiently converted to either cis- or trans-2,4,5-triarylimidazolines depending on the base used. A one-pot selective synthesis of cis- and transimidazolines from aromatic aldehydes was achieved under microwave irradiation.
