a Asymmetric synthesis of chiral allenes via enantioselective additions of activated 1,3-enynes. b Asymmetric stereodivergent catalysis was limited to the construction of point stereogenicity divergence. c Asymmetric stereodivergent construction of axial stereogenicity via modifications of chiral phosphoric acid catalysts.
