## Abstract Depending on the experimental conditions the spirolactone **3** on treatment with methylamine gave compounds **6, 7** or the rearranged product **4**. Compound **4** was used to prepare the title compounds **11–13, 15, 18–20** and other derivatives.
New derivatives of 3,4-dihydrospiro[cycloalkane- \(1^{\prime}, 2(1 H)\)-quinolines] were obtained from cycloheptanone and cyclooctanone via facile three steps hetero spiro annulation process. Their nitro derivatives were prepared through electrophilic substitution reactions.
