Substituted and fused spiro[benzo-2-azepine-3,1′-cyclohexanes]

5-Methyl-4,5-dihydro-3H-spiro[benzo-2-azepine-3,1′-cyclohexane] N-oxide was rear- ranged into 5-methyl-1-oxo-1,2,4,5-tetrahydro-3H-spiro[benzo- 2-azepine-3,1′-cyclohexane]. The latter was used for the synthesis of spiro{triazolo[3,4-a]- and-tetrazolo[5,1-a]beczo-2- azepinecyclohexanes}. © 2004 Springer Science+Business Media, Inc.
