Alkaline protease-catalyzed synthesis of quinazolinone derivatives was developed between β-keotester and o-aminobenzamide. Because ethanol is one kind of eco-friendly solvents, this method can reduce the impact of solvents on the environment. Alkaline protease as a biocatalyst has many advantages, e.g. high catalytic activity, environmentally friendly, wide variety of sources and simple operation. In addition, a variety of quinazolinone derivatives was obtained with good to excellent yields just using 2000 U alkaline protease as catalyst.

Key words: quinazolinone derivatives, biocatalysis, alkaline protease, ethanol, promiscuity
