Article abstract of DOI:10.1002/jhet.5570350135

New derivatives of 3,4-dihydrospiro[cycloalkane-1′,2(1H)-quinolines] were obtained from cycloheptanone and cyclooctanone via facile three steps hetero spiro annulation process. Their nitro derivatives were prepared through electrophilic substitution reactions.
