A new stereoselective route to isoanantine (1) and anantine (2) has been developed by the combination of three key steps : thiyl radical addition-cyclization of dienylamide, construction of the substituted imidazole, and stereoselective construction on the E-benzylidene moiety.
通过三个关键步骤的组合,开发了一条新的立体选择性路线,用于异氨基胍(1)和氨基胍(2)的合成:二烯基酰胺的硫醚基加成-环化、取代咪唑的构建以及E-亚苄基部分的立体选择性构建。
