A mild and efficient procedure for the synthesis of various 1,5-benzothiazepines were developed. This method provides an easy access for preparation of 1,5-benzothiazepine derivatives in the presence of 10 mol% catalyst of CAN under ultrasonic irradiation. This method provided clean conversion, mild reaction condition, no use of toxic solvent and shorter reaction time compared to other reported method.

of antimicrobial agents, we designed and synthesized novel tetrazole derivatives. The structures of compounds 6a–f and 7a–f were characterized by IR, 1H NMR, 13C NMR, MS and elemental analysis. These compounds were tested for their antimicrobialactivity against a series of strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa and for antifungal activity against

In the development of novel antimicrobial agents, we synthesized novel 1,2,3‐triazole‐based pyrazole and pyrimidine derivatives 6(a–f) and 7(a–f) by ultrasound‐assisted method. The synthesized compounds were characterized by IR, 1H NMR, 13C NMR, MS, and elemental analysis. All compounds were assessed in vitro for their efficacy as antimicrobial agents against four bacteria (Staphylococcus aureus, Bacillus
在新型抗菌剂的开发中,我们通过超声辅助方法合成了新的基于1,2,3-三唑的吡唑和嘧啶衍生物6(af)和7(af)。通过IR,1 H NMR,13 C NMR,MS和元素分析对合成的化合物进行表征。在体外评估了所有化合物作为抗四种细菌(金黄色葡萄球菌,枯草芽孢杆菌,大肠杆菌和铜绿假单胞菌)和两种真菌(白色念珠菌和黑曲霉)的抗菌剂的功效。)。特别地,化合物6a,6e,7a,7c和7e表现出高度有效的抗微生物活性。
