Fund Project: This research was partial supported by Beijing Institute of Technology.We are grateful to Perking University for NMR measurements and to Institute of Chemistry(Chinese Academy of Sciences) for numerous ESI-MS spectra and elemental analysis.

Two different skeletons of heterocyclic compounds, quinoline and quinazolinone analogs could be obtained by a novel one-pot synthesis from substituted 3-amino-lH-benzo[f]chromene-2-carbonitrile derivatives and cyclohexanone in DMF in the catalyst of anhydrous zinc chloride under reflux. A plausible mechanism was proposed.
- Friendländer cyclocondensation,
- Quinoline and quinazolinone analogs,
- New conversion
