Abstract: Tetrahydro-4H-pyrrolo[3,2-c]quinolin-4-ones and dihydro-1H-benzo[b]azepines are efficiently synthesized from 2-aminobenzonitriles and donor-acceptor cyclopropanes mediated by SnCl4 in moderate to good yields. The reaction involves the initial ring opening of a cyclopropane ring due to activation by SnCl4… read more here.
