Here we employed simple chemistry for the synthesis of a new potent series of benzo[b]thiophene containing 2-carbonylchlorides (1), 2-isopropyl carboxamides (2), 2-(piperidin-1-yl)-methanones (3) by nucleophilic chloro cyclocondensation of substituted-cinnamic acids with thionyl chloride to afford benzo[b]thiophene nucleus. The constitution of the products has been delineated by elemental analysis
在这里,我们采用简单的化学方法,通过以下方法合成了一系列新的强效的苯并[b]噻吩系列化合物:2-羰基氯化物(1),2-异丙基羧酰胺(2),2-(哌啶-1-基)-甲酮(3)。取代肉桂酸与亚硫酰氯的亲核氯环缩合,得到苯并[b]噻吩核。产品的组成已通过元素分析和光谱分析进行了描述。测定产品在不同浓度下的体外抗菌试验,并与可用的标准药物氨苄西林,氯霉素,环丙沙星,诺氟沙星和灰黄霉素进行比较。还研究了合成化合物的结构活性关系。标题化合物的初步体外生物学筛选显示,化合物2b,2c,2e,
