An Efficient, Green, and Solvent-free Multi-component Synthesis of Benzimidazolo/Benzothiazolo Quinazolinone Derivatives Using Sc (OTf)<sub>3</sub>Catalyst Under Controlled Microwave Irradiation
An efficient, fast, and green synthesis of benzimidazolo/benzothiazolo quinazolinone derivatives has been developed undersolvent‐free conditions by the reaction of 2‐aminobenzimidazole/2‐aminobenzothiazole, aromaticaldehydes, and 1,3‐diketones. This method extended the application of microwaveirradiation and scandium triflate combination and also tenders a lot of benefits such as excellent product
