1H NMR spectra of compounds 6. General Procedure. To a solution of enedione 5 (5 mmol) in acetonitrile (25 mL), the nitroalkane 1 (5 mmol) followed by DBU (5 mmol) were added at room temperature. After the solution was stirred for 6 h at room temperature, the solvent was evaporated at reduced pressure and the residue was purified by column chromatography (hexanes-ethyl acetate 8:2).

Conjugate addition of the nitroalkane to a cyclopentenone, before the elimination of the aldol, is also conceivable. At any event, this dehydration process should occur before the elimination of nitrous acid, since the presence of an acidic hydrogen at C-4 is necessary to afford the exocyclic double bond (see ref 9).
