Routes from substituted resorcinols to spiro-substituted dihydrobenzofurans are described.Whilst use of acid-catalysed condensations between a resorcinol and an aldehyde only gave low yields of dihydrobenzofurans and lacked regiocontrol, use of a nucleophilic aromatic substitution approach was successful.
