We report a protocol for palladium‐catalyzed dearomatizing alkoxydiarylation of furan rings via aerobic oxidative coupling between arylboronic acids and 5‐aryl‐2‐hydroxyalkylfurans. This green protocol starting from furan derivatives, which can be sustainably sourced, provides rapid access to polysubstituted 2,3,3a,6a‐tetrahydrofuro[3,2‐b]furans and hexahydrofuro[3,2‐b]furans, oxabicyclic frameworks
