A gold-catalysed synthesis of chromanes based on the intramolecular hydroarylation of allenes was investigated. The gold(I)-catalysed reaction tolerates electron-donating, neutral and weekly electron-withdrawing substituents such as halogens at the aromaticpart. The simple protocol that can be conducted at open flask conditions at room temperature delivering chromane derivatives which with a remaining
