title: Efficient sonochemical synthesis of thiazolidinones from piperonilamine.
abstract: An efficient multicomponent reaction of arenealdehydes, mercaptoacetic acid and piperonilamine under ultrasound irradiation to afford 2-aryl-3-(piperonylmethyl)-1,3-thiazolidin-4-ones is reported. Applying this methodology, eleven heterocycles were synthesized and isolated in good yields after short reaction times.
