摘要
Four novel bisoxazoline ligands 8a-d were synthesized from (S)-amino alcohols and could be formed effective catalysts (up to 77% ee for endo isomer) with Cu(OTf)(2) for enantioselective Diels-Alder addition. The facility of the reaction was dependent on the nature of the substituent R in the bisoxazoline ligand.
