  β-Sultams 水解的反应性和机理

  摘要：

  -与相应的无环磺酰胺的酸和碱催化水解相比，Sultams 的速率分别提高了 109 倍和 107 倍。它们的反应性比类似的 - 内酰胺高约 103 倍。一些 sultams 的碱性水解显示出一个速率项，它是氢氧根离子浓度的二级，这表明涉及三角双锥中间体 (TBPI) 的逐步机制。N-芳基-舒坦的碱性水解的Brnsted lg 值为-0.58，动力学溶剂同位素效应I 为0.60，与TBPI 的限速形成相容。相反，N-烷基--sultams 的 / 为 1.55，表明 TBPI 的限速分解。磺酰基的吸电子基团强烈阻碍了 -sultams 的酸催化水解，并提出该机制可能涉及单分子开环以产生磺酰离子。N-苄基-舒坦的酸催化水解的Brnsted lg值为0.32。羧酸对 N-苄基-舒坦的一般酸催化水解显示 0.67 的 Brnsted 值，这归因于特定的酸亲核机制，形成混合酸酐中间体。
