Glucose-Water Synergy: An Organocatalytic System Driven synthesis of Benzimidazolo[2,3-b]quinazolinone and Benzothiazolo[2,3-b]quinazolinone Derivatives

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.
