An efficient, fast, and green synthesis of benzimidazolo/benzothiazolo quinazolinone derivatives has been developed under solvent‐free conditions by the reaction of 2‐aminobenzimidazole/2‐aminobenzothiazole, aromatic aldehydes, and 1,3‐diketones. This method extended the application of microwave irradiation and scandium triflate combination and also tenders a lot of benefits such as excellent product yields, shorter reaction time, easy isolation of products, and environmentally benign reaction conditions.
