A simple and efficient Br?nsted acid catalyzed synthesis of 2‐aryl‐quinazolinones via cyclization of 2‐aminobenzamides with benzonitrile in PEG under metal and ligand‐free condition. All substituted benzonitriles were also well participated with the formation of the corresponding products in moderate to good yields.

Paragraph 0028-0031; 0054-0055, (2020/10/29)
The invention discloses a method for synthesizing a quinazolinone compound by photo-catalyzing alcohol oxidation in a water phase, which comprises the following steps: by taking a compound shown as aformula (I) and a compound shown as a formula (II) as raw materials and water as a solvent, adding a visible light catalyst, and reacting under the conditions of alkali and visible light to obtain a quinazolinone compound (III). The method for preparing the quinazolinone compound is environmentally friendly, easy and convenient to operate, safe, cheap and efficient. Compared with the prior art, the method is applicable to a large number of functional groups, high in yield, few in byproducts, simple and safe to operate, low in cost and environment-friendly; wherein R1 is H, C1-C4 alkoxy, halogen or nitro; and R2 is H, substituted or unsubstituted phenyl, 2-pyridyl, 2-thienyl or 5-methylfuryl.

Microwave-assisted copper-catalyzed cascade reactions between 2-halobenzoic acids and amidines to synthesize quinazolinone derivatives in water are reported. A variety of target products were obtained in good to excellent yields up to 94%. Its application was performed by the synthesis of 4-(1H-benzo[d]imidazol-2-ylthio)-6-methoxypteridine, which displayed significant anti-proliferation effect.
