The present invention is to provide an n-alkyl 3-amino-3-arylpropionate represented by the formula (I):
wherein Ar
1
represents an aryl group which may have a substituent(s), provided that a phenyl group and 4-methoxyphenyl group are excluded, R
1
represents an n-propyl group or an n-butyl group,
and a process for preparing the same, and its optically active compound and an optically active (S or R)-3-amino-3-arylpropionic acid represented by the formula (III-a):
wherein Ar represents an aryl group which may have a substituent(s), and * represents an asymmetric carbon,
and a process for preparing an optically active n-alkyl (R or S)-3-amino-3-arylpropionate represented by the formula (IV-a):
wherein Ar and R
1
have the same meanings as defined above, * represents an asymmetric carbon, provided that it has a reverse absolute configuration to the compound of the formula (III-a).

many types of cancer; therefore, eEF2K would be regarded as a promising therapeutic target. In this study, we discovered a β-phenylalanine scaffold by virtual high-throughput screening, as well as designed and synthesized 46 derivatives with assessment of inhibition activity against eEF2K and cytotoxicity. After several rounds of kinase and anti-proliferative activity screening, we discovered an eEF2K
