Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | DL-Phenylalanine, methyl ester | HCID 75737 | — |
| Reactant | N-(Benzyloxycarbonyl)-L-aspartyl-L-phenylalanine methyl ester | HCID 10159630 | — |
| Product | (R)-Methyl 2-amino-3-phenylpropanoate | HCID 853474 | 62.3% |
Reaction Steps
Example 17 was repeated except for using DL-phenylalanine methyl ester instead of L-phenylalanine methyl ester to obtain 756 mg of an addition compound of N-benzyloxycarbonyl-L-aspartyl L-phenylalanine methyl ester and D-phenyl alanine methyl ester (1:1) (melting point: 105° to 111° C.; yield: 62.3% based on N-benzyloxycarbonyl L-aspartic acid).
