New series of 2-(aryl or alkyl)-N-phenylhydrazine-1-carboxamides 1a–j were synthesized through one-pot reactions of aldehyde or ketones, hydrazine hydrate, and phenylisocyanate in MeOH. The structure of products was confirmed by Fourier transform infrared (FT-IR), proton nuclear magnetic resonance (1H NMR), and 13C NMR spectra. Minimum inhibitory concentration (MIC) of antibacterial activity of 1a–j was screened against five bacterial strains. Compound 1f showed antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus.
一系列新的2-(芳基或烷基)-N-苯基酰肼-1-羧酰胺化合物1a–j 通过醛或酮、水合肼和异氰酸苯酯在甲醇中的一锅法反应合成。产物的结构通过傅里叶变换红外光谱(FT-IR)、质子核磁共振(1H NMR)和13C NMR谱确认。对化合物1a–j的抗菌活性进行了最小抑菌浓度(MIC)筛选,针对五种细菌菌株。化合物1f显示对铜绿假单胞菌和大肠杆菌金黄色葡萄球菌具有抗菌活性。
