A catalytic and highly enantioselective intramolecular [4+2] cycloaddition of dieneynes was achieved by use of chiral iridium complex prepared in situ from [IrCl(cod)]₂ and BDPP [2,4-bis(diphenylphosphino)pentane]. The reaction proceeded in refluxed tert-butyl acetate to give chiral cyclohexa-1,4-dienes in very high enantiomeric excess.
