Nitroderivatives 9a-g have been prepared with great C-8 regioselectivity by allowing the corresponding 1, 2, 4, 5-tetrahydrospiro [3H-2-benzazepine-3, 1"-cycloalkanes] 8a-g to react with potassium nitrate and concentrated H 2 SO 4. The oxidative reaction of a nitrogen-carbon bond in spirobenzazepines 8 and 9 was performed with H 2 O 2 and catalytic amounts of sodium tungstate at room temperature affording nitrones 10a-d in moderate to high yields. Stereochemical assignments for all the 2-benzazepine derivatives obtained
