Production method and its derivatives α- amino acids using the same and optically active quaternary ammonium salt having axial chirality

摘要

The present invention discloses a method of producing the amino acids and derivatives α- condition, and its optically active quaternary ammonium salt having axial asymmetry. Optically active quaternary ammonium salt having axial asymmetry of the present invention is a chiral phase transfer catalyst can be produced with less structure is more simple process. Is very useful in the synthesis of its derivatives and dialkyl α- -α- amino acids, and their derivatives and α- -α- alkyl amino acid α as a phase transfer catalyst, the compounds of the present invention, in the development of pharmaceuticals and novel food can be used.
