A method for the synthesis of previously unknown heterocyclic systems 4‐((5‐(difluoromethoxy)‐1H‐benzo[d]imidazol‐2‐ylthio)methyl)tetrazolo[1,5‐a]quinolines derivatives 6 has been developed based on various substitutes 2‐chloroquinoline‐3‐carbaldehydes 1 via the consecutive steps of conversion into tetrazolo[1,5‐a]quinoline‐4‐carbaldehyde 2 on treatment with sodium azide which upon reduction to the
已开发出一种合成先前未知的杂环系统4-((5-(二氟甲氧基)-1H-苯并[d]咪唑-2-基硫基)甲基)四唑并[1,5-a]喹啉衍生物6的方法。在各种替代2-氯喹啉-3- carbaldehydes 1 经由转换的连续步骤为四唑并[1,5-a]喹啉-4-甲醛2上用叠氮化钠处理,其在还原成相应的醇衍生物3,转化为氯化物4用亚硫酰氯,然后与5-(二氟甲氧基)-1 H-苯并[d]咪唑-2-硫醇5偶联。合成标题化合物(6a筛选了6b,6b,6c,6d,6e)对革兰氏阳性和革兰氏阴性细菌的抗菌活性。J.杂环化学。(2010)。
