Intramolecular [2 + 2] cycloaddition of ketenimines with imines. Synthesis and chemical behaviour of azeto[2,1-b]quinazolines

Azeto[2,1-b]quinazolines 5 have been prepared by the novel intramolecular [2 + 2] cycloaddition reaction of ketenimines with imines. The applicability and limitations of the synthetic methodology, and explorations on the reactivity of compounds 5 are discussed.
