Michael-type addition of 1,5-diazabicyclo [ 4.3.0 ] non-5-ene (DBN) with methyl 2-perfluoroalkynoates (2) occurred and subsequent intramolecular condensation of the adduct gave a tricyclic derivative(3). The structure of 3 was confirmed by elemental analysis, IR, MS and 1H NMR,13C NMR, 13C-1H cosy, 1H-1H cosy . The reaction mechanism was also proposed.
