Abstract
Methyl 2-aryl-2H-azirine-3-carboxylates are good dienophiles. They react with cyclopentadiene, cyclohexa-1,3-diene and 2,3-dimethylbuta-1,3-diene at or below 50°C to give products of [4+2]-cycloaddition to the carbon-nitrogen double bond. The cycloadditions are endo selective and the dienophiles approach from the less hindered face of the azirines.
