The synthesis of a range of bicyclic Diels–Alderadducts (structures b) of cyclopentadiene with symmetrical and unsymmetrical azodicarbonyl compounds is described. Thermal isomerization of these adducts to the bicyclic 1,3,4-oxadiazines (structures c and d) is especially rapid with bulky acyl groups. In unsymmetrical adducts with acyl groups of markedly different size, the larger group dictates completely
描述了一系列环戊二烯的双环 Diels-Alder 加合物(结构 b)与对称和不对称偶氮二羰基化合物的合成。这些加合物对双环 1,3,4-恶二嗪(结构 c 和 d)的热异构化对于庞大的酰基特别快。在具有明显不同大小的酰基的不对称加合物中,较大的基团完全决定了异构化的方向。具有两个不同芳酰基的加合物产生两种异构体。描述了加合物、恶二嗪和恶二嗪的二氢衍生物的光谱性质。
