| 摘 要： | The Diels-Alder reaction is the most useful method for six-membered ring formation1. As a consequence, a number of effective enantioselective processes have been developed over the years 2-4. Of particular interest, metal bisoxazoline complexes formed fro…

| Abstract: | 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. |
