A variety of dihydroquinazolin-4(1H)-onederivatives (1–37) were synthesized via “one-pot” three-component reaction scheme by treating aniline and different aromatic aldehydes with isatoic anhydride in the presence of acetic acid. Chemical structures of compounds were deduced by different spectroscopic techniques including EI-MS, HREI-MS, 1H-, and 13C-NMR. Compounds were subjected to α-amylase and

A simple, efficient, and general method has been developed for one-pot, three-component synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives based on a condensation reaction strategy of isatoic anhydride, aldehydes, and amines using acetic acid under reflux conditions.
Convenient and Scalable Synthesis of 2,3-Dihydroquinazolin-4(1<i>H</i>)-one Derivatives and Their Anticancer Activities
InBr3-catalyzed approach to synthesize 2,3-dihydroquinazolin-4(1H)-onederivatives (3a–3aa) has been developed. Notably, all the products were isolated by recrystallization and the reaction is accessible on a gram scale. Moreover, the reactions only require 10–60 min. All the synthesized compounds were evaluated for their in vitro anticanceractivity against four human cancer cell lines. GRAPHICAL ABSTRACT
