Alk. protease-catalyzed synthesis of quinazolinone derivatives I [R = H, 7-Me, 6-Cl; R1 = Me, Et, n-Pr; R2 = Me, Et] was developed between β-keotesters and o-aminobenzamides. Because ethanol is one kind of eco-friendly solvents, this method could reduce the impact of solvents on the environment. Alk. protease as a biocatalyst had 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 alk. protease as catalyst. In the experimental materials used by the author, we found Methyl 3-oxovalerate(cas: 30414-53-0Recommanded Product: Methyl 3-oxovalerate)
Methyl 3-oxovalerate(cas: 30414-53-0) belongs to ketone compounds. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups.Recommanded Product: Methyl 3-oxovalerate
