A synthetic route to the epibatidine analogue endo-5-(6-chloro-3-pyridyl)-2-azabicyclo[2.2.1]heptane and the corresponding endo-6- isomer is described, starting from a readily-available 2-azabicyclo[2.2.1]hept-5-ene derivative. Both the exo-5- and exo-6- compounds are also shown to be accessible from the same substrate using reductive Heck chemistry.
从易于获得的2-氮杂双环开始,描述了一种合成表异丁烷类似物的内部-5-(6-氯-3-吡啶基)-2-氮杂双环[2.2.1]庚烷和相应的内部-6-异构体的合成途径。[2.2.1]庚-5-烯衍生物。两个外型-5-和外-6-化合物也显示出是从使用还原的Heck化学在同一基板访问。
