  3,4-二硝基噻吩开环的合成开发。可使用1,4-二取代的2,3-二硝基-1,3-丁二烯和2,3-丁二酮二肟

  摘要：

  3,4-二硝基噻吩1与伯胺或仲胺的优化开环反应可生成1,4-双（烷基氨基）-和1,4-双（芳基氨基）-2或1,4-双（二烷基氨基） -2，3-二硝基-1，3-丁二烯3具有令人满意的优异收率。溶液中的化合物2似乎是（Z，Z），（Z，E）和（E，E）立体异构体的混合物，其组成受溶剂性质的影响，而化合物3却显示为单一的（E，E）异构体。的反应3与THF中的各种有机金属化合物表示未知的新型接入（E，E）-1,4-二烷基和（E，E）-1,4-二芳基-2,3-二硝基-1,3-丁二烯4。最后，4的两个硝基乙烯基官能团的Pb还原有效地导致相应的对称的1,4-二取代的2,3-丁二酮二肟5。
