Abstract

Up to now, derivatives of usnic acid were only prepared by classical methods of refluxing in organic solvents for hours. In this study, we examined the condensation reaction of usnic acid with o-toluidine under microwave irradiation condition which gave good yield in a short time. The obtained optimal condition was applied to prepare some other derivatives of (+)-usnic acid.
