Two homologous series of diastereoisomeric racemic +/- cis and +/- trans-N,N-dimethyl-N-alkyl-2-benzoyloxycyclohexylmethylammonium bromides with the number of carbon atoms in the alkyl chain from six to twenty (m = 6,8 ... 20) were synthesised. Their structures have been elucidated by IR, UV and in some cases also with 1H and 13C NMR spectrometry. The title compounds were assayed for their antimicrobial
两个非对映异构体外消旋的+/-顺式和+/-反式N,N-二甲基-N-烷基-2-苯甲酰氧基环己基甲基溴化铵的同源系列,烷基链中的碳原子数为六到二十(m = 6,8 ... 20)已合成。其结构已通过IR,UV以及某些情况下的1H和13C NMR光谱得以阐明。分析标题化合物对微生物金黄色葡萄球菌,大肠杆菌和白色念珠菌的抗微生物活性。观察到对金黄色葡萄球菌的抗菌活性最高(log 1 / MIC = 5.5 mol-1 dm3),对大肠杆菌的抗菌活性最低(log 1 / MIC = 4.5 mol-1 dm3)。
