Enantioenriched (S)-6,6′-diphenylBinol-Ca: A novel and efficient chirally modified metal complex for asymmetric epoxidation of α,β-unsaturated enones

Article abstract of DOI:10.1016/j.tetasy.2003.08.022

A novel enantioenriched-Ca complex was generated using low cost commercially available CaCl₂ and the potassium salt of (S)-6,6′-diphenylBINOL and its application to α,β-unsaturated enone epoxidation is described. Furthermore the absolute stereo
