A method for the synthesis of bi- and tricyclic amidines has been developed through copper-catalyzed aerobic [3+2]-annulation reaction of N-alkenyl amidines. These cyclic amidines could be converted into mono-benzyl-protected vicinal diamines by the reduction with aluminum hydride.
一种双环和三环脒的合成方法已经通过铜催化的 N-烯基脒的有氧[3+2]-环化反应发展起来。这些环状脒可以通过氢化铝还原转化为单苄基保护的邻二胺。
