Facile syntheses of 2H-chromenes or 9-functionalizedphenanthrenes under mild conditions in moderate to good yields have been developed. They each involve annulations of arynes with α,β-unsaturatedcompounds bearing different electron-withdrawing groups (EWGs). Depending on the natures of the different EWGs, the reactions proceed by different pathways: enals react with arynesthrough a tandem [2+2]
