An object of the present invention is to provide a method for producing an optically active amino acid in high yield and in a highly enantioselective manner, which method has fewer restrictions on the material that can be used as the substrate, and to provide, among others, a compound useful as a chiral auxiliary for the method. The present invention provides an N-(2-acylaryl)-2-[5,7-dihydro-6H-dibenzo[c,e]azepin-6-yl]ac etamide compound represented by Formula (1):
or a salt thereof, or a metal complex represented, by Formula (3):
