PROBLEM TO BE SOLVED: To provide a new method by which an optically active amine compound or its derivative can asymmetrically be synthesized from an inexpensive raw material in high catalyst-utilizing efficiency in mild reaction conditions.小林 修...
The enantiomer selection in the nucleophilic addition reaction of optically active amines such as [alpha]-amino acid esters to phenylalanine and N-methylphenylalanine N-carboxyanhydride in m-dimethoxybenzene as a solvent has been investigated. Stereoselectivity between the amines and the N-carboxyanhydrides...
