form has been obtained by the interaction of cotarnine with bromine. The reaction of 9-bromocotarnine with α-haloketones is accompanied by the extension of the six-membered hetero-ring to seven-membered ring and led to previously unknown 4-acyl-9-bromo-3-methyl-6-methoxy-7,8-methylendioxy-1,2-dihydro-3-benzazepines. Some of these compounds have been shown to have only moderate antibacterial (against
摘要9-溴可豆碱稳定的高氯酸盐形式已通过可豆碱与溴的相互作用获得。9-bromocotarnine 与 α-haloketones 的反应伴随着六元杂环延伸到七元环,并导致了以前未知的 4-acyl-9-bromo-3-methyl-6-methoxy-7 ,8-methylendioxy-1,2-dihydro-3-benzazepines。这些化合物中的一些已被证明仅具有中等的抗菌(针对金黄色葡萄球菌、大肠杆菌)和抑菌(意大利青霉)活性,但它们都没有显示出对 Colpoda steinii 的显着杀原生生物活性。
