以邻苯二胺、乳酸、芳香胺为原料合成了 5种未见文献报道的苯并咪唑Schiff碱类化合物(3a～ 3e) .所有化合物均经元素分析、红外光谱、紫外光谱、核磁共振谱确证 .抑菌活性测试表明它们具有比较好的抑菌能力 Five novel benzimidazole Schiff base compounds (3a ~ 3e) were synthesized from o-phenylenediamine, lactic acid and aromatic amines. All the compounds were characterized by elemental analysis, IR, UV and NMR Confirmed. Antibacterial activity tests show that they have better antibacterial capacity
