Synthesis of fisetin and 2′,4′,6′-trihydroxydihyrochalcone 4′-O-β-neohesperidoside based on site-selective deacetylation and deoxygenation

Fisetin and 2′,4′,6′-trihydroxydihyrochalcone 4′-O-β-neohesperidoside were synthesized from commercially available quercetin and naringin in five steps. The key steps are site-selective deacetylation and subsequent deoxygenation. The target molecules were obtained in 37% and 23% yields from the starting materials, respectively.
