Abstract:
Introduction: A simple and efficient one-pot synthesis of quinazolinone derivatives has
been developed via a multicomponent reaction (MCR) involving the condensation of dimedone,
benzaldehyde, and 2-aminobenzimidazole/2-aminobenzothiazole.
Method: In this work, glucose water is used as a green, reusable, environmentally benign organocatalytic
solvent system to synthesize desired products.
Result: The main benefits of this one-pot method include its excellent yields, less time, cost-effectiveness,
atom economy, environment benign, and easy workup.
Conclusion: In conclusion, we successfully developed a green protocol for the environmentally
benign synthesis of benzimidazo/benzothiazolo quinazolinones using glucose water as an organocatalytic
medium.
