| titleOfInvention | Synthesis method of beta-benzo amino acid compound |
| abstract | The invention relates to a preparation method of a beta-benzo amino acid compound, which comprises the following steps: (1) obtaining a racemate compound shown as a formula (I); (2) reacting a racemate compound shown as a formula (I) with L-aspartic acid to obtain a compound shown as a formula (I-1); and/or reacting the racemate compound shown in the formula (I) with D-aspartic acid to obtain a compound shown in the formula (I-2); (3) introducing a protecting group on an amine group in the compound shown in the formula (I-1) and/or the compound shown in the formula (I-2), and then carrying out a transesterification reaction. The synthesis method can obtain the beta-benzo amino acid compounds with different configurations without chiral chromatographic resolution, has low cost, simple operation and convenient industrial application, and the product has high chiral purity and high yield. |
