A new class of methyleneamine‐linked bis‐heterocycles that exhibit antimicrobial activity was synthesized. Bromination of 1 followed by condensation with thiourea gave 3. The reaction of 3 with propargyl bromide in dry toluene under inert atmosphere led to the formation of 4. Its subsequent reaction with different aromatic azides 5 using CuSO4.5H2O‐sodiumascorbate system in a 2:1 mixture of water and
合成了一类新的具有抗菌活性的亚甲胺连接的双杂环。溴化1,然后与硫脲缩合,得到3。在惰性气氛下,3与炔丙基溴在无水甲苯中的反应导致形成4。随后在水和叔丁基醇的2:1混合物中使用CuSO 4 .5H 2 O-抗坏血酸钠体系与不同的芳族叠氮化物5反应,得到标题化合物6a,6b,6c,6d,6e,6f,6g,6h,6i,6j的产量很高。通过元素分析,IR,1 H,13 C NMR和质谱研究证实了这些化合物的身份。所有标题化合物均表现出明显的体外抗菌和抗真菌活性。J.杂环化学。(2011)。
