Abstract

The application of sonochemistry for the synthesis of different coumarins from active methylene compounds and 2-hydroxybenzaldehydes or resorcinol was very effective on a multigram scale with a higher yield, higher amount of crystalline compound, and shorter reaction time compared with the compounds obtained using the classical procedures.
