Firstly, 24 chiral Schiff base ligands were prepared and evaluated for theasymmetric HDA reaction between Brassard diene with benzaldehyde. Theresults revealed that the ligand derived from 3,5-di-tert-butylsalicylaldehydewith (1R,2S)-2-amino-1,2-diphenyl-1-ethanol shows an excellent chiralinduction in the reaction.
