This invention relates to a "one pot" process for the preparation of isoserine derivatives in high diastereoselective way. The process according to the invention includes the steps of reacting a protected glycidic acid with imines to yield isoserines protected both at the -OH and at the -COOH groups, deprotection of the obtained intermediates to isoserines or isoserine 1-4C- alkyl esters. Pure threo derivatives as the main isomer are obtained.

L-threo-β-benzyloxyaspartate derivatives having a substituent on the benzene ring, represented by the following formula (1):
wherein R is hydrogen, a linear or branched lower aliphatic acyl group with the acyl portion optionally substituted, an alicyclic acyl group, an aromatic acyl group with a substituent on the aromatic ring, an amino acid-derived group or a biotin derivative-derived group, having an amino substituent on the benzene ring, and salts thereof, which can easily bind to affinity column chromatography carriers as ligands of glutamate transporter proteins.

The present invention relates to photosensitive derivatives of optically active L-threo-β-benzyloxyaspartate or its benzene ring-substituted analogs, represented by the following formula (1) or (2): (1) (2) wherein R1 represents hydrogen atom, amino group, straight or branched lower aliphatic acylamino group optionally substituted at the acyl group portion, alicyclic acylamino group or aromatic acylamino group optionally having a substituent on the aromatic ring, R2 represents hydrogen atom or one or more straight or branched optionally substituted lower aliphatic alkyloxy groups on the benzene ring, R3 represents hydrogen atom, methyl group or carboxyl group, and R4 and R5 each represent hydrogen atom, hydroxyl group, straight or branched lower alkyloxy group optionally substituted at the alkyl portion, amino group, straight or branched lower alkyl-substituted amino grop, or a halogen atom, which upon photoirradiation can produce compounds exhibiting a function of suppressing the glutamate uptake activity of L-glutamate transporters.
