  Synthesis of Substituted Indoline and Carbazole by Benzyne-Mediated Cyclization–Functionalization

  摘要：

  A benzyne-mediated synthesis of substituted indolines and carbazoles was developed. The reaction includes generation of benzyne using Mg(TMP)(2)center dot 2LiCl as a base, cyclization, and trapping the resulting organomagnesium intermediate with an electrophile to provide a series of substituted indolines and carbazoles in a regiospecific manner. This was applied to a concise five-pot total synthesis of heptaphylline.

• Synthesis of Carbazole Alkaloids by Ring‐Closing Metathesis and Ring Rearrangement–Aromatization

  Aprocess for the assembly of carbazole alkaloids has been developed on the basis of ring‐closing metathesis (RCM) and ringrearrangement–aromatization (RRA) as the key steps. This method is based on allyl Grignard addition to isatin derivatives to provide smooth access to 2,2‐diallyl 3‐oxindole derivatives through a 1,2‐allyl shift. The diallyl derivatives were used as RCM precursors to afford a novel

  咔唑生物碱的组装工艺是在关键步骤闭环复分解（RCM）和环重排芳构化（RRA）的基础上开发的。该方法基于烯丙基格利雅（Irally Grignard）除以伊斯丁衍生物之外，从而通过1,2-烯丙基转移可平稳地获得2,2-二烯丙基3-氧吲哚衍生物。二烯丙基衍生物用作RCM前体，以提供一类新的螺环戊烯-3-氧吲哚衍生物，该衍生物经过新颖的RRA反应以提供咔唑衍生物。通过在正交串联催化过程中结合RCM和RRA步骤，缩短了咔唑的合成顺序。咔唑生物碱的直接合成进一步证明了这种方法的实用性，其中包括阿莫konal衍生物，girinimbilol，heptaphylline，

  The DIBAL‐H promoted reductive pyran ring opening of dialkylpyrano[3,2‐a]carbazoles provides a direct access to a broad range of prenyl‐ and geranyl‐substituted carbazoles. Formation of a pyran ring followed by reductive ring opening represents a new method for the introduction of prenyl and geranyl groups. In the course of the present work, we achieved the first total syntheses of the following eight

  their potential effect on wild-type and mutant p53 activity using a yeast screening assay and on human tumor cell lines. Naturally-occurring carbazoles 1–3 showed the most potent growth inhibitory effects on wild-type p53-expressing cells, being heptaphylline (1) the most promising in all the investigated cell lines. However, compound 1 also showed growth inhibition against non-tumor cells. Conversely

  在约50％的人类癌症中，抑癌基因p53通过突变而失活。结合并稳定那些突变体的小分子可能代表有效的抗癌药。在本文中，我们报告了咔唑生物碱和氨基衍生物对肿瘤细胞生长的抑制活性，以及​​它们对p53的潜在激活作用。从七氢茶碱（1），7-甲氧基七氢茶碱（2）和7-甲氧基粘康糖醛（3）分离了十二种氨基咔唑生物碱，而七氯甲碱是从克劳森纳（Clausena harmandiana）分离得到的。，使用还原胺化方案。使用酵母筛选试验和人类肿瘤细胞系评估了天然存在的咔唑1-3及其氨基衍生物对野生型和突变型p53活性的潜在影响。天然存在的咔唑1-3对七型茶碱对野生型p53表达细胞具有最强的生长抑制作用（1）是所有研究过的细胞系中最有前途的。然而，化合物1也显示出针对非肿瘤细胞的生长抑制。相反，半合成的氨基咔唑1d在表达野生型和突变型p53的肿瘤细胞中表现出有趣的生长抑制活性，对非肿瘤细胞的生长抑制作用很低。酵母

  New tacrine–carbazole hybrids were developed as potential multifunctional anti-Alzheimer agents for their cholinesterase inhibitory and radical scavenging activities. The developed compounds showed high inhibitory activity on acetylcholinesterase (AChE) with IC50 values ranging from 0.48 to 1.03 μM and exhibited good inhibition selectivity against AChE over butyrylcholinesterase (BuChE).

• Synthesis and cytotoxic activity of the heptaphylline and 7-methoxyheptaphylline series
  作者：Tula Thongthoom、Pawantree Promsuwan、Chavi Yenjai

  日期：2011.9

  Nineteen carbazole alkaloids modified from heptaphylline (I) and 7-methoxyheptaphylline (II) isolated from Clausena harmandiana were synthesized. Among these derivatives, Ih and IIi showed cytotoxicity against the NCI-H187 cell line with IC50 values of 0.02 and 0.66 mu M, respectively, which are about 138 and 4 fold stronger than the ellipticine standard. In addition, oxime Ih displayed cytotoxicity against KB cells with an IC50 value of 0.17 mu M which is about 10 times stronger than the ellipticine. This compound demonstrated weak cytotoxicity against Vero cells (IC50 = 66.01 mu M). The results show convincingly that Ih may be a promising lead for the development of cytotoxic agents.
