N-(4-bromophenyl)furan-2-carboxamide (3) was synthesized by the reaction furan-2-carbonyl chloride (1) and 4-bromoaniline (2) in the presence of Et3N in excellent yields of 94%. The carboxamide (3) was arylated by employing triphenylphosphine palladium as a catalyst and K3PO4 as a base to afford N-(4-bromophenyl)furan-2-carboxamide analogues (5a-i) in moderate to good yields (43–83%). Furthermore,
N- (4-溴苯基)呋喃-2-甲酰胺( 3 )由呋喃-2-碳酰氯( 1 )和4-溴苯胺( 2 )在Et 3 N存在下反应合成,收率高达94%。通过使用三苯基膦钯作为催化剂和 K 3 PO 4作为碱将甲酰胺 ( 3 ) 芳基化,以中等至良好的产率 ( 43– 83%)。此外,我们研究了各个化合物对临床分离的耐药细菌鲍曼不动杆菌的体外抗菌活性,肺炎克雷伯菌、阴沟肠杆菌和金黄色葡萄球菌。与各种市售药物相比,发现分子 ( 3 ) 对这些细菌,特别是 NDM 阳性细菌鲍曼不动杆菌具有最有效的活性。对接研究和 MD 模拟进一步验证了它,表达了活性位点和分子相互作用的稳定性。
