2,5-Oxyarylation of Furans: Synthesis of Spiroacetals via Palladium-Catalyzed Aerobic Oxidative Coupling of Boronic Acids with α‑Hydroxyalkylfurans

Abstract

A protocol for the 2,5-oxyarylation of furan rings via Pd-catalyzed aerobic oxidative coupling of boronic acids with α-hydroxyalkylfurans is reported. This protocol provides rapid, green access to diverse biologically interesting and synthetically useful unsaturated spiroacetals from sustainable furan derivatives
