title: Bioinspired construction of a spirocyclohexadienone moiety via sodium nitrite catalyzed aerobic intramolecular oxidative phenol coupling.
abstract: An efficient and green intramolecular oxidative phenol coupling for the direct construction of spirocyclohexadienones has been developed, which uses environment-friendly sodium nitrite as the catalyst and oxygen in the air as the terminal oxidant. Hydroxy-containing substituted phenanthrenes and dibenzoazepines could be easily obtained from the dienone-phenol rearrangement.
