Abstract :
The condensation of aromatic aldehydes, cyclopentanone and urea promoted by nano Al2O3-SO3H and HCl (aq) as heterogeneous and homogeneous catalysts, respectively, have been developed for the synthesis of some arylidene heterobicyclic compounds. In this synthesis, we have used two methods with sonication and thermal condition that have several advantages such as excellent yields and short reaction times. The ultrasonic device used in this study includes an ultrasonic bath equipped with a thermal system designed and built in our laboratory.
