A practical phosphoric acid-catalysed double/triple Pictet-Spengler annulation/oxidative aromatization has been developed to synthesize a series of C2- and C3-symmetrical quinazolinones from 2-aminobenzamides and aldehydes. The products can be easily transformed into various valuable aromatic diamines and triamines with different substitute side chains in gram-scale, which might be potential for exploration of new functional materials.

Key words: Phosphoric Acid-Catalysis, Pictet-Spengler Annulation, C2/C3-Symmetry, Quinazolinone
