AbstractDirect reductive amination of 1,3-diphenyl-1H-pyrazole-4-carbaldehyde and 3-(4-methylphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde with various substituted aromatic amines using NaBH4 in the presence of I2 as reducing agent is described. The reaction has been carried out in anhydrous methanol under neutral conditions at room temperature. The structure of newly synthesized diphenyl pyrazolylmethylanilines
摘要1,3-二苯基-1-的直接还原胺化ħ吡唑-4-甲醛和3-(4-甲基苯基)-1-苯基- 1 H ^ -吡唑-4-甲醛通过使用硼氢化钠的各种取代的芳族胺4在存在描述了I 2作为还原剂。该反应已在无水甲醇中在室温下于中性条件下进行。基于IR,1 H,13建立了新合成的二苯基吡唑基甲基苯胺的结构1 H NMR和质谱数据。在体外测试了所有二苯基吡唑基甲基苯胺衍生物对不同菌株的真菌和细菌的抗真菌和抗菌活性。大多数化合物表现出相当大的抗真菌活性,但对测试菌株的抗菌活性却很差。 图形概要
