SYNTHESIS OF DEHYDRO-3,3′-BIS(p-HYDROXYCINNAMOYL)-5,5′-METHYLENEDIFILICINIC ACID, AN ANALOG OF CARTHAMIN
In connection with the studies on the structure of carthamin (1), dehydro-3,3′ -bis(p-hydroxycinnamoyl)-5,5′-methylenedifilicinic acid, an analog of 1, was synthesized from 2-benzoylphloroglucinol through five steps and its properties were compared with those of 1.
