Abstract A new method was found for the synthesis of pyrazoleacetate esters from pyrazolaldehyde. By a new tandem reaction, in which 4-pyrazoleacetate esters reacted with carbon disulfide and iodomethane, thieno[2,3-c]pyrazole was synthesized. This was an easy method for the synthesis of this type of heterocycles.
摘要 发现了一种以吡唑醛为原料合成吡唑乙酸酯的新方法。通过新的串联反应,其中4-吡唑乙酸酯与二硫化碳和碘甲烷反应,合成了噻吩并[2,3-c]吡唑。这是合成此类杂环的一种简单方法。
