    A cascade process involving an SN2′ reaction and an intramolecular oxa-Michael addition has been developed by treating Morita–Baylis–Hillman acetates of nitroalkenes with arenols, such as β-naphthols, α-naphthols, and substituted phenols under basic conditions. The products, arenofurans, are formed as single regioisomers in good to excellent yield in most cases. The methodology has been successfully
