制备方法与用途

用途

CN201810227822.1报道了一种抗肿瘤药物AZD9291的制备方法，以2-溴-4-甲氧基苯胺为起始原料，通过硝化反应、格式反应、酰化反应、还原反应、格式反应和消去反应，最终得到AZD9291游离碱。该发明具有以下优点：原料来源广、成本低、操作简单、溶剂可回收再利用、废液排放量小、产品回收率高等，易于实现产业化。

合成方法

向含有2-溴-4-甲氧基-1-硝基苯（1.7 g, 7.33 mmol）的MeOH（30 mL）溶液中加入氯化铵（7.84 g, 147 mmol）和锌粉（4.79 g, 73.3 mmol）。在室温下搅拌混合物1小时后，LCMS结果显示反应已完成。随后除去MeOH，并将残余物用EtOAc/饱和碳酸氢钠溶液稀释，在室温下搅拌10分钟后过滤以去除不溶性物质。收集滤液并进行有机层的盐水洗涤和硫酸钠干燥处理，最后浓缩。使用120 g ISCO柱（0-100％EtOAc/己烷洗脱40分钟）纯化粗样品，并收集期望级分后浓缩，得到2-溴-4-甲氧基苯胺。

  sulfenylated indoles via an intermolecular reaction. Cyclic voltammetry (CV) and density functional theory studies suggest that benzothiazole formation proceeds via a mechanism that involves an electrophilic sulfur radical, while the indole sulfenylation likely proceeds via a nucleophilic sulfur radical adding into a radical cationic indole. These conditions were successfully extended to several thiobenzamides

  我们报告了光催化形成 C-S 键以通过分子内环化形成苯并噻唑和通过分子间反应形成磺基化吲哚的研究。循环伏安法 (CV) 和密度泛函理论研究表明，苯并噻唑的形成通过涉及亲电硫自由基的机制进行，而吲哚磺基化可能通过亲核硫自由基加入自由基阳离子吲哚进行。这些条件已成功扩展到几种硫代苯甲酰胺和吲哚底物。
