Sonochemistry as a General Procedure for the Synthesis of Coumarins­, Including Multigram Synthesis

Authors: Pinto, L.S.; De Souza. M.V.N.


Abstract

This study describes a general procedure for the synthesis of different coumarins via sonochemistry using active methylene compounds and 2-hydroxybenzaldehydes or resorcinol. The application of sonochemistry for the synthesis of these compounds was also 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.
