products depending on the substiuents at the C-4 and C-5 positions. In particular, the presence of a pyrimidinyl substituent induces some noticeable changes in the reaction pathway, yielding a novel heterocycle whose synthesis has not been previously reported.
乙硫醇钠在取代的1,2-二硫代-3-硫酮的S-2位反应,生成各种产物,具体取决于C-4和C-5位的取代基。特别地,嘧啶基取代基的存在在反应途径中引起一些明显的变化,从而产生了一种新的杂环,其合成以前没有被报道过。
