The present invention relates to a novel substitution The present invention relates to a preparation method and activity research of a novel substituted 4,6-dihydroxy-3(2H)-benzofuranone derivative. The invention uses phloroglucinol as a raw material to obtain arurone derivatives with potential biological activity through Friedel-Crafts acylation reaction, alkali-catalyzed cyclization reaction, electrophilic substitution reaction, aldol condensation reaction and a series of reactions. |
