Abstract:
Chiral 1,2-amino alcohols were synthesized via newly developed &ldquo<br>intramolecular unsaturation transfer&rdquo<br>using cyclohexanone, propargyl bromide, and various chiral amino alcohols as starting components. These amino alcohols can be potential chiral ligands for many asymmetric transformation reactions. Therefore, their effectiveness as chiral ligands in diethylzinc addition to benzaldehyde and N-diphenylphosphinoyl imines were tested. Various parameters including temperature, solvent, ligand amount etc. were screened for the synthesized chiral ligands. In diethylzinc addition to be

Due to the importance of α-amino acids, numerous efficient methods for their asymmetric synthesis have been growing rapidly. Although these methods can provide good yields and enantiomeric excesses of α-amino acids, some of them suffered from requiring the use of strong bases under low temperatures or resulting in poor or no recovery o
