Abstract
Chiral heteroorganic N-trityl aziridine alcohols and aziridine ethers have proven to be highly efficient catalysts in enantioselective conjugate diethylzinc additions to enones, namely chalcone and 2-cyclohexen-1-one providing the desired chiral adducts in high chemical yields (up to 95%) and with ee’s up to 93%. The change of the absolute configuration of the stereogenic center located at the aziridine moiety on the stereochemical outcome is also discussed.
