Optically active quaternary ammonium salt having axial asymmetry, and method for producing alpha-amino acid and derivative thereof by using the same |
摘要 |
The present invention discloses an optically active quarternary ammonium salt having axial asymmetry and a method for producing an α-amino acid and a derivative thereof using the same. The optically active quarternary ammonium salt having axial asymmetry of the present invention is a chiral phase-transfer catalyst that has a simple structure and that can be produced in a smaller number of process steps. The compound of the present invention is very useful as a phase-transfer catalyst in the synthesis of an α-alkyl-α-amino acid and a derivative thereof as well as an α,α-dialkyl-α-amino acid and a derivative thereof. Therefore, the compound of the present invention can be used in the development of novel foods and pharmaceuticals. |
