摘要

Abstract Novel heterocycles, 4H-tetrazolo [1, 5-a][1] benzazepines 6 were prepared by the intramolecular 1, 3-dipolar cycloaddition reaction of azidophenylcyanomethyl compounds 5. The latter were readily obtained from 2-azidobenzaldehyde through the Baylis-Hillman adducts 3 followed by acetylation to compounds 4 and nucleophilic substitution by cyanide to compounds 5.
