## Abstract Dihydroquercetin (dhq) and its 3-acetate react with acetic anhydride in the absence of a base catalyst to yield mixtures of partially acetylated products. Three new esters were characterized by NMR spectroscopy as dhq 3,7,3โ€ฒ-triacetate, 3,7,4โ€ฒ-triacetate and 5,7,3โ€ฒ,4โ€ฒ-tetraacetate. At i
