from condensation of various aromatic aldehydes with cyclopentanone and cyclohexanone. All synthesized compounds were characterized by nuclear magnetic resonance (NMR), infrared (IR), and mass spectroscopy and X-ray single-crystal analysis. The synthesized compounds were screened for their in vitro antimicrobial and antifungal activity. Good antimicrobial activity, especially against methicillin-resistant
5,6-二氢-4 H-环戊[ b ]-噻吩-2-羧酸和4,5,6,7-四氢苯并[ b ]的一系列新的亚芳基衍生物通过使氯醛的亚苄基衍生物与2-巯基乙酸反应来合成]-噻吩-2-羧酸。氯醛的亚苄基衍生物是由2-苄叉基环戊酮和2-苄叉基环己酮衍生物的Vilsmeier反应制得的,该衍生物是由各种芳族醛与环戊酮和环己酮的缩合反应制得的。所有合成的化合物均通过核磁共振(NMR),红外(IR)以及质谱和X射线单晶分析进行表征。筛选合成的化合物的体外抗微生物和抗真菌活性。对于大多数测试化合物,观察到良好的抗菌活性,尤其是对耐甲氧西林的金黄色葡萄球菌。特别是化合物9f 作为有效的抗菌剂出现,并且可能是未来药物发现和开发的潜在候选者。
