  Novel bis(indolyl)hydrazide–hydrazones as potent cytotoxic agents

  摘要：

  A series of bis(indolyl) hydrazide-hydrazones 5a-n were synthesized and evaluated for their cytotoxicity against selected human cancer cell lines. The reaction of indole-3-carboxaldehyde 2 with indole-3-carbohydrazide 4 in presence of catalytic amount of acetic acid afforded 5a-n in good yields. Among the synthesized bis(indolyl) hydrazide-hydrazones, the compound 5b with N-(p-chlorobenzyl) and bromo substituents was found to be the most potent against multiple cancer cell lines (IC(50) = 1.0 mu M, MDA-MB-231). The compound 5k exhibited selective cytotoxicity against breast cancer cell line MCF7 (IC(50) = 3.1 mu M). (C) 2011 Elsevier Ltd. All rights reserved.

• Iridium(<scp>iii</scp>) catalyzed regioselective amidation of indoles at the C4-position using weak coordinating groups
  作者：Veeranjaneyulu Lanke、Kandikere Ramaiah Prabhu

  Herein we disclose a simple and short synthetic route for the amidation of indoles at the C4 position by employing an aldehyde as a directing group and Ir(III) as a catalyst. This strategy offers high selectivity for the C4-amidation of unprotected and protected indoles. A simple deprotection of the tosyl group leads to the formation of C4-amino indole derivatives, which are useful synthons for synthesizing

  在几种天然产物和生物活性化合物中经常遇到C4胺化的吲哚支架。本文中，我们公开了通过使用醛作为导向基团和Ir（III）作为催化剂来使吲哚在C4位酰胺化的简单且短的合成路线。该策略为未保护的和被保护的吲哚的C4酰胺化提供了高选择性。甲苯磺酰基的简单脱保护导致形成C 4-氨基吲哚衍生物，其是用于合成调心素家族中的天然产物的有用的合成子。

  Bischler (or Bischler-Mohlau) reaction between aromatic amines and alpha-bromoketones has been studied by computational and experimental techniques. It has been found that in many cases the reaction yields are improved under microwave irradiation and working in the absence of solvent. When di- and trisubstituted amines are used as substrates the regioselectivity of the reaction is different to that obtained

  已通过计算和实验技术研究了芳香胺和α-溴代酮之间的Bischler（或Bischler-Mohlau）反应的范围和区域选择性。已经发现，在许多情况下，在微波辐射下和在没有溶剂的情况下工作，反应产率得到提高。当使用二和三取代的胺作为底物时，反应的区域选择性与相应的伯苯胺所获得的区域选择性不同。在相同条件下，苯1,2-二胺和α-溴苯乙酮之间的反应可生成2-取代的喹喔啉，而不是吲哚。最后，当使吡啶-2-胺和嘧啶-2-胺与相应的α-溴乙酰苯反应时，得到相应的咪唑并[1,2-a]吡啶和咪唑并[1,2-a]嘧啶，

  of ethyl diazoacetate (EDA) to 2-aminobenzaldehydes cleanly affords the indole core. As opposed to other common approaches for the synthesis of indole, this method displays both excellent functional group tolerance and perfect regiochemical control. This allowed the synthesis of a variety of useful indole building blocks from 2-aminobenzaldehydes derived from readily available anthranilic acids.

  已经开发了温和，有效和简单的合成3-乙氧基羰基吲哚的方法。将重氮乙酸乙酯（EDA）添加到2-氨基苯甲醛中可干净地获得吲哚核。与其他常见的吲哚合成方法相反，该方法显示出出色的官能团耐受性和完美的区域化学控制。这允许由衍生自容易获得的邻氨基苯甲酸的2-氨基苯甲醛合成多种有用的吲哚结构单元。

  1,1,1,3,3,3-Hexafluoropropan-2-ol (HFIP) was found to be effective for the Bischler indole synthesis under microwave irradiation in the absence of a metal catalyst. Under the catalysis of HFIP, a wide range of α-amino arylacetones were successfully transformed into indole derivatives with moderate to good yields.
