2-Aroylcyclohexanones, obtained from piperidinocyclohexene, react with hydrazine, hydroxylamine, and o-phenylenediamine to give the corresponding derivatives of bicyclic heterocycles – indazole, 2,1-benzisoxazole, and 2-spiro-cyclohexylbenzimidazole. The structure of a derivative of benzyloxazole has been determined by X-ray crystallography.
