制备方法与用途

应用 4-溴靛红是一种有机溴化物，可用作医药合成中间体。

制备方法 4-溴靛红的制备步骤如下：

1. 将3-溴苯胺（0.05 mol）、盐酸羟胺（0.15 mol）、硫酸钠（0.35 mol）、2N 盐酸和水合氯醛（0.06 mol）溶解于 250 mL 水中，在 90℃ 下反应 2 小时。通过 TLC 检测确认反应完全后，进行过滤并减压浓缩，直接进入下一步反应。
2. 向搅拌的浓硫酸溶液（20 mL）中分批加入步骤1得到的化合物，并将混合物加热至65℃。使用TLC分析确认反应完成后，冷却至室温并将反应混合物倒入冰水中（250 mL）。用水洗涤沉淀并干燥，然后用 5% NaOH 水溶液溶解粗产物，并用4NHCl（20 mL）酸化后过滤、洗涤和干燥，最终得到化合物3b（两步总产率64％）。

  摘要：

  严重急性呼吸系统综合症 (SARS) 是由 SARS-CoV 引起的严重危及生命且致命的呼吸道疾病。SARS-CoV 含有与主要小核糖核酸病毒蛋白酶 3CL pro类似的胰凝乳蛋白酶样主要蛋白酶。3CL pro在病毒复制周期中起着关键作用，是 SARS 抑制剂开发的潜在目标。设计、合成了一系列靛红衍生物作为可能的 SARS-CoV 3CL pro抑制剂，并通过使用荧光底物肽的体外蛋白酶测定进行评估，其中几种对 3CL pro显示出有效的抑制作用. 分析了构效关系，并通过分子对接研究提出了可能的结合相互作用模式。在所有化合物中，8k 1对 3CL pro显示出最有效的抑制活性(IC 50  = 1.04 μM)。这些结果表明，这些抑制剂有可能被开发成抗 SARS 药物。

  A new enantioselective approach to obtain a tetrasubstituted chiral center at the C3 position of oxindoles via a catalytic asymmetric Morita–Baylis–Hillman reaction has been demonstrated. This reaction provides 3‐substituted 3‐hydroxy‐2‐oxindoles in good to excellent yields and ee values, which could be facilely transformed to pharmaceutically more interesting compounds.

  The asymmetric cross-aldol reaction of isatins with α,β-unsaturated ketones has been developed under catalysis by a Cinchona alkaloid-derivated bifunctional Brønsted acid–Brønsted base catalyst, affording the aldol adducts in moderate to good yields (18–98%) with moderate to good enantioselectivities (30–97%). The noncovalent organo-catalyzed asymmetric cross-aldol reaction displays a broad substrate
