Synthesis of Bicyclic Imidazole, 1,2,4-Triazole and 1,3,5-Triazine Derivatives from N-Cyanolactam 2-Imines

Paetzel, Michael,Bohrisch, Joerg,Liebscher, Juergen

, p. 975 - 978 (2007/10/02)

N-Cyanolactam 2-imines 1 are versatile N-C-N-C building blocks for the synthesis of partially saturated bicyclic compounds.Reactions with acidic methyl halides, hydroxylamine O-sulfonic acid, and phenyl isocyanate afford bicyclic imidazole (4), 1,2,4-triazole (6), and 1,3,5-triazine (8) derivatives, respectively. Key Words: N-Cyanolactam 2-imines / 1,2,4-Triaoles, bicyclic / 1,3,5-Triazines, bicyclic
