Fig. 2 四环烷结构式及球棍模型在逆合成分析过程中，两个课题组均采用了一个新颖独特的合成策略：首先通过[2+2+2]环化反应，形成基本的骨架结构；然后通过ROCM开环-催化氢化反应，引入两个乙基和相应的手性中心

下一篇文章将会介绍这个配体的铬/镍/亚铜配合物制备路线分为两步：第一步：环化反应2-氰基吡啶与水合肼在乙醇中回流，通过[4+2]环化反应生成3,6-二(2-吡啶基)-1,4-二氢-1,2,4,5-四嗪（

2个甲酰基，均具有良好反应活性，可以对哌嗪引入我们想要的基团，从而得到各种HEDC哌嗪与不同二胺化合物进行环化缩合反应，再对产物进行硝化等取代反应，可以得到一系列高能化合物，比如DFTHP与脲进行稠环化反应生成
