摘要
N-Metallo imines derived from benzaldehyde such as N-aluminium imine, N-boryl imine and N-silyl inline,were asymmetrically alkylated with butyllithium iri the presence of chiral ligands including (-)-sparteine and proline-derived amino alcohols to give optically active 1-phenylpentyl-1-amine in up to 74 % enantiomeric excess. Polymer-supported chiral ligands were also used for the asymmetric addition.
