  在酸性介质中用肼和苯肼将5-酰基嘧啶环化为4-酰基吡唑

  摘要：

  5-苯甲酰基-4-甲基嘧啶4a，b和5-乙酰基-4-苯基嘧啶5a，b与肼在酒精酸性介质中反应，分别得到4-乙酰基-3-苯基吡唑7、9和10以及4-苯甲酰基-3-甲基吡唑6、8和11。在与苯肼的反应中，5-苯甲酰基-4-甲基-2-甲基硫代嘧啶（4a）仅导致4-乙酰基-1,3-二苯基吡唑（10），而5-乙酰基4-苯基-2-甲基硫代嘧啶（5a）导致4-苯甲酰基-3-甲基-1-苯基吡唑（11）通过嘧啶4a和3d的苯hydr的初始形成5a。然而，5-苯甲酰基-4-甲基-2-苯基嘧啶（4b）和5-乙酰基-2,4-二苯基嘧啶（5b）与苯肼反应，以各自提供两种异构的吡唑的混合物。讨论了这些环收缩反应的机理。

  In the present work, an efficient regioselective synthesis of 1,3,4-tri- and 1,3,4,5-tetrasubstituted pyrazoles via a methanesulfonic acid (MSA)-catalyzed reaction of hydrazones with enaminones or enamines is reported. Mechanistically, the formation of the title compounds involves the [2+3] cycloaddition of hydrazones with enaminones or enamines followed by aromatization with acid and oxygen. This
