The syntheses of seven 4-(substituted phenyl)but-2-en(or yn)yl quaternary ammonium salts and four related tertiary amines are described. The Meerwein arylation reaction was the preferred synthetic method for the required intermediate 1-aryl-4-halo-2-butenes (15a-c, 18). In the case of 18, the trans stereochemistry of the Meerwein adduct of 2,3-dimethylbutadiene was established unambiguously by 2D NMR
描述了七个4-(取代的苯基)丁-2-烯(或炔基)季铵盐和四个相关的叔胺的合成。Meerwein芳基化反应是所需中间体1-芳基-4-卤代-2-丁烯(15a-c,18)的优选合成方法。对于18,通过2D NMR和X射线研究明确地确定了2,3-二甲基丁二烯的Meerwein加合物的反式立体化学。标题化合物代表III类抗心律不齐药clofilium(1)的构象受限类似物,并且在使用分离的犬浦肯野纤维进行的体外评估中显示出可比的效能和功效。这些结果表明1中的亚烷基链以活性构象延伸。计算机辅助构象分析(MM2)支持这一结论。
