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.
