and cyclocondensation, in the same pot to afford diverse 4-arylthio-1,2-naphthoquinones 2, 4-arylthio-1,2-diacetoxynaphthalenes 3, and 5-arylthio-/5-aminobenzo[a]phenazines 4 in very good isolated yields. The multistep single-pot synthesis occurs smoothly in DMF at rt.
1,2-萘醌及其衍生物构成了与药物和材料化学相关的重要化合物。结果表明,由邻碘氧苯甲酸介导的2-萘的氧化反应生成的1,2-萘醌可以在同一锅中进行一连串的反应,即氧化,迈克尔加成,还原,乙酰化和环缩合,得到多样4-芳硫基-1,2-萘醌2,4-芳基硫基-1,2- diacetoxynaphthalenes 3,和5-芳硫基/ 5-氨基苯并[一个]吩嗪4中很好的分离产率。多步单锅合成在rt的DMF中顺利进行。
