| titleOfInvention | A procedure to synthesize Levorotatory P-Hydroxyphenylglycine compounds |
| abstract | The present invention relates to the field of chemical synthesis, in particular to a process for synthesizing levorotatory p-hydroxyphenylglycine compounds, which eliminates subsequent resolution processes, racemization processes, etc., simplifies the operational steps; and small organic molecule acids are chosen as catalyst in the second stage, which not only leads to the realization of an industrialized production, but also makes the ee value of the final products 88.1-98.0% determining the catalyst, the reaction solvent, the reactive substance, the reaction temperature and the duration of the reaction; a non-aqueous solvent is used in the second stage to avoid the discharge of residual water containing phenol, whereby environmental pollution is reduced. |
