文摘In the work, a study of mass fragmentation routes by the electron-impact mass spectrometry data has been examined for two open chain intermediates of indole derivatives and two pyrroloquinolines. By the isolation of open chain intermediate and the mass spectra, the structures of pyrroloquinoline have been confirmed.
