METHOD FOR PRODUCING HYDROXYLATED CHALCONES AND FLAVANONES

摘要

The purpose of the present invention is to provide an easy method for producing hydroxylated chalcones and flavanones.　The present invention relates to a method for producing hydroxylated chalcones and flavanones, the method being characterized in that bismuth chloride is used.　In a demethoxymethylation step, target chalcones or target flavanones are obtained efficiently as a single product, and thus the present invention can provide an effective method for producing chalcones and flavanones where purification is easily performed.
