Abstract
The oxidation and reduction of 4,5-dihydro-5-methyl-3H-spiro[benz-2-azepine-3,1'-cyclohexane] N-oxide, the reactions of this N-oxide with methylmagnesium iodide, the sodium salt of diethyl malonate, phenyl isocyanate, and its rearrangement by the action of acetic anhydride lead to N-hydroxy-1,2,3,4-tetrahydrobenz-2-azepines, benz-2-azepine-1-one, and its N-acetoxy derivative as well as isoxazolidino- and oxadiazolidino[3,2-a]benz-2-azepines spirofused with a cyclohexane ring.
