yields compared to the analogous N-Ts compounds. The success with the N-Bus aziridines facilitated the development of a new route to the spirocyclic core of the histrionicotoxins and completion of a formal synthesis of (+/-)-perhydrohistrionicotoxin.
在20个有机锂介导的β-烷氧基氮丙啶转化为取代的烯丙基磺酰胺的例子中,有18个例子,与类似的N-Ts化合物相比,在氮上使用Bus(Bus = t-BuSO2)取代基的产率更高。N-Bus氮丙啶类化合物的成功促进了一条通往组氨酸毒素螺环核心的新路线的开发,并完成了(+/-)-perhydrohistrionicotoxin的正式合成。
