| titleOfInvention | (r)-praziquantel preparation method |
| abstract | The present invention relates to an (R)-praziquantel preparation method, comprising steps of using (R,S)-tetrahydroisoquinoline-1-formate or salts thereof, or 1-(S)-tetrahydroisoquinoline-1-formate or salts thereof as a raw material to prepare 1-(R)-tetrahydroisoquinoline-1-formate salts, and steps of preparing (R)-praziquantel from said 1-(R)-tetrahydroisoquinoline-1-formate salts. The preparation method for 1-(R)-tetrahydroisoquinoline-1-formate or salts thereof is as follows: perform an oxidation reaction between the raw material described above and oxygen in the presence of recombinant D-amino acid oxidase and catalase, then perform a reduction reaction on the resulting product under the effect of a borane-amine complex, thus successively converting 1-(S)-tetrahydroisoquinoline-1-formate or salts thereof into the 1-(R)-tetrahydroisoquinoline-1-formate or salts thereof isomer. The present method not only produces an (R)-praziquantel product with a high optical purity, but is also low-cost and environmentally friendly in terms of production. |
