It is provided that a method for producing an optically active bisamidoalcohol compound represented by the formula (3):
wherein R1 represents a C1-6 alkyl group, an optionally substituted phenyl group, an optionally substituted aralkyl group or a hydrogen atom, or two R1s, which are bonded to the same carbon atom, are bonded to form a ring together with the carbon atom to which they are bonded,
R2 represents a C1-6 alkyl group, an optionally substituted phenyl group, a 1-naphthyl group, a 2-naphthyl group or an optionally substituted aralkyl group,
R3 and R4 are the same or different, and each represents a hydrogen atom or C1-3 alkyl group,
m represents an integer of 0 to 2, and
* represents an asymmetric center, which comprises reacting an optically active aminoalcohol compound represented by the formula (1):
wherein R1, R2 and * are as defined above,
with a diester compound represented by the formula (2):
wherein R3, R4 and m are as defined above and R5 represents a C1-3 alkyl group,
in the presence of a lithium compound.
