The present invention is to provide a method for producing the desired optically active β-amino acid derivatives of high optical purities in high yields, without requiring a step of deprotection. More particularly, the present invention relates to a method for producing an optically active β-amino acid derivative or a salt thereof represented by the formula (2):
which comprises reacting an α,β-unsaturated carboxylic acid derivative or a salt thereof represented by the formula (1):
with an amines or a salt thereof in the presence of a chiral catalyst and in the presence or absence of an acid.
Disclosed are compounds of the formula
