The first enantioselective conjugate alkynylation of beta-trifluoromethyl alpha,beta-enones using terminal alkynes and a taniaphos-Cu(I) complex as catalyst is described. Ketones bearing a trifluoromethylated propargylic chiral centre in the beta-position were obtained with good yields and high enantiomeric excesses (up to 99%).
