A series of 5-(2-nitro-l-phenyl)ethyluracils were obtained when β-nitrostyrenes were reacted with 1,3-di-methyl-6-substituted uracil derivatives, instead of cyclic compounds. The structures of the compounds 5, 6, and 7 were proved by spectroscopic methods and their mass fragmentation patterns are discussed.
当β-硝基苯乙烯与1,3-二甲基-6-取代的尿嘧啶衍生物而不是环状化合物反应时,获得了一系列的5-(2-硝基-1-苯基)乙基尿嘧啶。通过光谱方法证明了化合物5、6和7的结构,并讨论了其质量碎片模式。
