Abstract A DABCO‐promoted intermolecular cyclization between enols and nitrostyrenes has been developed for the regioselective synthesis of angularly fused furan derivatives in high yields. This protocol is applicable to various enol derivatives, including 4‐hydroxyquinolinones, 4‐hydroxycoumarin, and 4‐hydroxypyranone.
