(1), isolated from the skin of the Ecuadoran poison frog was synthesized in racemic form starting from tropinone. Distinctly different from the previously published approaches, this synthesis features the novel synthesis of the 7-azabicyclo[2.2.1]heptane ring system by contraction of the tropinone skeleton viaFavorskii rearrangement. Five analogues of 1 were also prepared, and their analgesic activities
从厄瓜多尔毒蛙的皮肤中分离出的非鸦片止痛药Epibatidine(1)是从托皮酮开始以消旋形式合成的。与先前公开的方法截然不同,该合成的特征是通过Favorskii重排通过肌钙蛋白骨架的收缩来合成7-氮杂双环[2.2.1]庚烷环系统。还制备了5个1的类似物,并评估了它们的镇痛活性。
