With the use of microwave irradiation, licoagrodione was prepared from Claisen rearrangement of the corresponding allyl phenyl ether 1,2-diketone readily available from the Lindlar's reduction of the corresponding alkyne derivative. Subsequent removal of protecting groups then furnished the desired product. © 2008 American Chemical Society.Mahidol UniversityChemistryArticleSCOPUS10.1021/jo8013353
