Synthesis of novel fluorinated flavonols via Algar-Flynn-Oyamada reaction
Flavonols have attracted considerable attention due to their diverse biological effects. However, naturally occurring flavonols are typically present only in low concentrations, with fluorine-containing flavonols being especially rare. In that respect, the construction of diverse flavonol analogues…
