An efficient β-cyclodextrin catalyzed multicomponent synthetic protocol has been developed for the synthesis of spiro[indoline-3,2'-quinazoline]-2,4'(3’H)-dione from isatoic anhydride, isatin and primary amine in aqueous medium. This methodology offers a convenient method for the synthesis of spiroindole quinazolines in excellent yields. To extend synthetic utility of protocol some dihydro quinazolines

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
Synthesis of 2,3-Dihydroquinazolin-4(1<i>H</i>)-ones by Three-Component Coupling of Isatoic Anhydride, Amines, and Aldehydes Catalyzed by Magnetic Fe<sub>3</sub>O<sub>4</sub> Nanoparticles in Water
A simple and efficient protocol for one-pot three-component coupling of isatoic anhydride, amines, and aldehydes in water using magnetically recoverable Fe3O4 nanoparticles is reported. This methodology results in the synthesis of a variety of 2,3-dihydroquinazolin-4(1H)-ones in high yields. The catalyst can be recovered and recycled without a significant loss in the catalytic activity.

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
