A method was developed for the annulation of the tetrahydrothiadiazine moiety to the imidazole and benzimidazole rings through intramolecular cyclization of S-alkyl derivatives of aminomercaptoimidazoles and -benzimidazoles. The factors controlling the stereoselectivity of the formation of the tetrahydrothiadiazine ring were revealed.
