4-Dimethylaminopyridine-catalyzed benzannulation reaction of aromatic 1,3-diketones with 3-butyn-2-one providing highly substituted benzenes was developed under mild conditions. The structure of product was confirmed on the basis of 1H NMR, 3C NMR and HRMS techniques.

Key words: 4-dimethylaminopyridine, 3-butyn-2-one, highly substituted benzene
