The present invention relates to the method of preparing chiral chromanes and chromenes in high yields by intramolecular hydroarylation of chiral aryl alkynes catalysed by either a silver(I) or gold(I) salt or complex in combination of a specific acid or by a silver(I) or gold(I) metal salt or complex having specific anion. By the hydroarylation a chromene is formed which has a chiral centre in the 2 position. The corresponding chromane is obtained by hydrogenation of the chromenes.
