reactivity of acetamidrazones I in strong basicity conditions was examined. When compounds I are reacted with equivalent quantities of α-haloketones in sodium alcoholate, the pyrrolidino[2,3-c]pyrazol-3-ones IV were obtained by intermediate formation of 1-acyl-3-amino-5-pyrazolones III.
检查了乙酰氨基dra酮I在强碱性条件下的反应性。当化合物I与等量的α-卤代酮在乙醇酸钠中反应时,通过中间形成1-酰基-3-氨基-5-吡唑啉酮III可获得吡咯烷并[2,3 - c ]吡唑-3-酮IV。
