    Abstract: 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.

    Abstract: The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of formula of a specific type and of at least one urea or thiourea.
