| Abstract
| - N-(1-Cycloalkenyl)pyrroles 3a,b, -pyrazoles 6a,b, and -imidazoles 9a,b were synthesized viaelimination of benzotriazole or 5-phenyltetrazole from the corresponding 1-[1-(heterocycyl)cycloalkyl]benzotriazoles 2, 5, and 8 or 1-[1-(heterocycyl)cyclohexyl]-5-phenyltetrazole (12 and 14). Intermediates 2, 5, 8, 12 and 14 were obtained by cyclizations of dihaloalkanes with N-(benzotriazol-1-ylmethyl)heterocycles, 1-imidazol-1-ylmethyl-5-phenyltetrazole (11), or 1-pyrazol-1-ylmethyl-5-phenyltetrazole (13) in the presence of n-BuLi.
