Resumen:
One-pot syntheses of 5H-[1,3]thiazolo[2,3-b]quinazolin-5-one, 12H-[1,3]benzothiazolo[2,3-b]quinazolin-12-one, and corresponding derivatives were developed using the copper-catalyzed Ullmann condensation. The use of ultrasonic irradiation enhanced yields and reduced the reaction time to minutes.
