through cyclization, and the subsequent C-S bonding with 2-bromoacetophenones gave the desired 2-substituted thiobenzoazoles containing α-sulfenylated aromatic ketones smoothly. The method features transition metal-free, simple operation, mild conditions, short reaction time, and good yields, showing potential synthetic value for the synthesis of a variety of biological or pharmaceutically active compounds
报道了一种以罐法有效合成2-取代硫代苯并唑的方法。因此,二硫化四甲基秋兰姆(TMTD)与2-氨基苯硫酚、2-氨基苯酚或1,2-苯二胺反应,通过环化形成2-巯基苯并杂环,随后与2-溴苯乙酮CS键合,得到所需的含有α的2-取代硫代苯并唑。 -磺酰化芳香酮顺利进行。该方法不含过渡金属,操作简单,条件温和,反应时间短,收率好,对合成多种生物或药物活性化合物具有潜在的合成价值。
