The present invention relates to a novel chiral phase-transfer catalyst, and a method for preparing an alpha-amino acid by using the same. According to the present invention, an alpha-amino acid of high optical purity could be synthesized in a high yield under an easy industrially applicable reaction condition by using a novel cinchona alkaloid compound as a chiral phase-transfer catalyst, and thus the present invention can be used as a key technique of the asymmetric alpha-amino acid synthesis and preparation field.
