Phenylalanine is one of the necessary amino acids, but until now it has been produced in small quantities and has only been used as an amino acid. Recently, with the gradual increase in the use of amino acids and logical liquids, demand has been increasing as a raw material for pharmaceutical synthesis and for the artificial sweetener α-L-aspartyl-phenylalanidimethyl ester (aspartame). Furthermore, since D-phenylalanine also has an inflammatory effect, there has been a need to isolate optically active phenylalanine in a small size.

(は見当らない。On the other hand, it has been reported that when L-phenylalanine is allowed to act on DL-mandelic acid, an L-phenylalanine/L-mandelic acid complex crystallizes (Nichikkashi 9'2.999 (
(1971)), but there is no report that D-phenylalanine can be optically separated by optically active mandelic acid.

f:見い出した。Based on these facts, the inventors of the present invention have developed a method for producing optically active phenylalanine that is industrially more processable and inexpensive.
As a result of repeated studies, it was discovered that by using optically active mandelic acid, DL-phenylalanine could be optically resolved into derivatives with high purity and commercial yield without derivation.
