A convenient approach for the synthesis of tetrasubstituted pyrazoles is described. The method involves the treatment of 1,3-diketones and allyltrimethylsilane with CAN followed by cerium-catalyzed addition of substituted hydrazines to construct pyrazoles in good yields.
描述了一种合成四取代吡唑的简便方法。该方法包括用 CAN 处理 1,3-二酮和烯丙基三甲基硅烷,然后在铈催化下添加取代的肼,以高产率构建吡唑。
