PROCESS FOR THE REGIOSELECTIVE SYNTHESIS OF L-ALKYL-3-HALOALKYLPYRAZOLE-4-CARBOXYLIC ACID DERIVATIVES |
| 摘要 |
The present invention relates to a process for the regioselective synthesis of 1-alkyl-3-haloalkylpyrazole-4-carboxylic acid derivatives by cyclization of 2,3-disubstituted acrylic acid derivatives with hydrazines, in the presence of carbonyl com-pounds. |
