Using water as a green reaction media, aldehydes or ketones react with 2-aminobenzohydrazide to give hydrazone firstly, and then a series of quinazolinone derivatives are obtained by the reaction of the hydrazone with another molecule of aldehyde or ketone catalyzed by 1 mol% Yb(OTf)3. This method provides several advantages such as neutral conditions, high yields (80%~94 %), simple work-up and environmental benignity. The structures were established by spectroscopic data of IR, 1H NMR and HRMS techniques.

Key words: 2-aminobenzohydrazide, quinazolinone, water, Yb(OTf)3
