  Intermolecular and Intramolecular α-Amidoalkylation Reactions Using Bismuth Triflate as the Catalyst

  摘要：

  Bismuth(III) triflate was found to promote the formation of stable cyclic N-acyliminium species in remarkable catalytic amounts (1 mol %). The alpha-amidoalkylation process seems to be effective in intermolecular and intramolecular manners leading to alpha-substituted lactams and heterocyclic systems containing azacycles, respectively. By comparing our results with those obtained with the classical Lewis acids as catalysts, it was evidenced clearly that the use of bismuth(III) triflate had been efficient for nearly all alpha-acetoxy lactams we used, except for N-acyliminium precursors bearing a sulfur atom. Also, the process seems to be easy, general, and clean, having diastereoselectivity comparable to protocols using classical Lewis acids and resulting in the formation of polyheterocyclic systems in good to excellent yields (64-99% in acetonitrile as solvent).

  The synthesis, in vitro evaluation and SAR studies of 67 maleimides and derivatives acting as antifungal agents are reported. A detailed SAR study supported by theoretical calculations led us to determine that: an intact maleimido ring appears to be necessary for a strong antifungal activity, dissimilarly affected by the substituents in positions 2 and 3. The best activities were shown by 2,3-nonsubstituted

  报道了67种马来酰亚胺及其衍生物作为抗真菌剂的合成，体外评估和SAR研究。由理论计算支持的详细SAR研究使我们确定：完整的马来酰亚胺环似乎对于强的抗真菌活性是必需的，与位置2和3上的取代基不同。然后是2,3二氯和2-甲基取代的马来酰亚胺。它们都是杀真菌剂，而不是抑真菌剂，增强了其抗真菌活性的重要性。2,3-二甲基和2,3-二苯基-马来酰亚胺具有边际活性或无效活性。N中存在灵活的连接链-苯基烷基马来酰亚胺似乎不是抗真菌活性所必需的，尽管其长度显示出与抗真菌行为的相关性，显示出烷基链为n  = 3和n  = 4的马来酰亚胺是大多数真菌中最佳的抗真菌活性。苯环上的不同取代基对活性没有明显的影响。化学势性质以及能量的值不能充分区分活性化合物和非活性化合物。尽管如此，发现尽管log  P单凭其强度不足以正确预测其抗真菌活性，对同一亚型化合物的抗真菌活性值的比较表明，抗真菌活性随亲脂性的增加而增强。另
