title: Catalyst-free sonosynthesis of highly substituted propanamide derivatives in water.
abstract: A clean, rapid and energy-efficient approach to catalyst-free one-pot synthesis of highly substituted propanamide derivatives in water was developed utilizing of the ultrasonic irradiation. The method has been successful in achieving the green chemistry objective. A catalyst-free operation, an energy efficient protocol using ultrasound irradiation instead of conventional heating or stirring and use of water as a non-hazardous, inexpensive and readily available solvent in the one-step reaction against sequential reaction steps thus combining the features of both economic and environmental advantages.
