Abstract
The N-arylimines of 2-(alk-2-enyl)amino-4-oxo-4H-pyrido[1,2-a]pyrimidine-3-carbaldehyde undergo the intramolecular [4+2] cycloaddition reaction under Lewis acid-catalyzed conditions to afford diastereomeric tetraazapentaphene derivatives. The diastereoselectivity as well as the scope and limitations of the cycloaddition reactions is discussed.
