Abstract

Abstract: Natural products icaritin and β-anhydroicaritin with P-glycoprotein(P-gp) inhibitory activities were efficiently synthesized in nine steps from commercially available phloroglucinol. A modified Algar-Flynn-Oyamada cyclization and relay Claisen-Cope rearrangement were employed in this concise route. Our synthesis offers opportunities to synthesize various icariin analogues for biological and pharmacological investigations.

Key words: Icaritin, Flavonol, Regioselectivity, Algar-Flynn-Oyamada
