| titleOfInvention | Synthetic method of pyrrole derivative |
| abstract | The invention discloses a method for preparing pyrrole derivatives, which comprises the following steps of adding a proper reaction solvent into a container filled with phosphine ylide, sequentially adding isocyanate and amine compounds, stirring at normal temperature, then adding silver nitrate, continuously stirring until the reaction is finished, carrying out reduced pressure distillation and concentration to remove the solvent, and carrying out column chromatography separation on a crude product to obtain a target product pyrrole derivative, wherein the reaction formula is as follows: the method has the advantages of simple and convenient operation, mild conditions, wide substrate application range, cheap and easily-obtained raw materials, low cost, high yield of target products and the like. |
