The first practical asymmetric version of the intermolecularPauson-Khandreaction has been developed based on novel chiral (non-racemic) alkoxy acetylene dicobalt hexacarbonyl complexes. The major adduct from (1R, 2S)-2-phenylcyclohexyloxyethyne and norbornadiene, isolated in 58% yield, is shown to be useful for obtaining chiral 4-substituted 2-cyclopentenones.
