A method is proposed for introducing one, two, or three alkyl substituents into positions 4 and 6 of the cyclohexane-1, 3-dione molecule by successive alkylation under the action of strong bases. (±)-Angustione (a natural β-diketone) has been synth

The primary fraction of the total ion current in the mass spectra of decahydro-4-quinolones and 4-alkyl-2-methyldecahydro-4-quinolols containing various substituents in the 1, 4, and 7 positions is due to fragments with ammonium ion structures.
