This paper presents the synthesis of epibatidine analogues by a straightforward one-pot method for the synthesis of 7-azabicyclo[2.2.1]heptane-1-carbonitriles, starting from cyclohexanones bearing a leaving group at the 4-position. In situ imine formation, followed by reversible cyanide addition, allows complete conversion of 4-(mesyloxy)cyclohexanone to the bicyclic core. Elaboration of the introduced
本文介绍了通过简单的一锅法合成 7-氮杂双环 [2.2.1] 庚烷-1-腈,从在 4 位带有离去基团的环己酮开始合成表巴替丁类似物。原位亚胺形成,然后是可逆的氰化物加成,允许 4-(甲磺酰氧基)环己酮完全转化为双环核。对引入的腈官能团和叔胺的脱保护的精心设计产生了五种新的表巴替丁类似物。
