Abstract

High-intensity ultrasound was employed to reinvestigate the aldol reaction in water. A number of aldols that would eliminate or form side products under conventional conditions were isolated in good yields within minutes. The results are highly reproducible because the sonochemical parameters were rigorously controlled.
