  Synthesis and anti-tumor activity of novel combretastatins: combretocyclopentenones and related analogues

  摘要：

  A series of 2-(3,4,5-trimethoxyphenyl)-3-arylcyclopent-2-ene-1-ones (8a-8e) and their related analogues, including pentenone 9a, pentenol 10a, pentene 12a, and furane 15, were synthesized and evaluated for cytotoxicity against murine and human tumor cell lines. Compounds 8a-c, 8e and 9a showed strong cytotoxicity with IC50 values in the range of 8-34 ng/mL. Compound 8e exhibited significant anti-tumor activity in BDF1 mice bearing Lewis lung carcinoma cells with an inhibition ratio of 59%. (C) 2002 Elsevier Science Ltd. All rights reserved.

  The bromination of 2,3-diarylcyclopent-2-en-1-ones under various conditions has been studied. It was found that depending on the brominating reagent and nature of solvent the bromine atom can be introduced at the 4- or 5-position of the ethene “bridge”, as well as into the aryl moieties. Aryl group bromination is accomplished with such reagents as molecular bromine, N-bromosuccinimide, or tetrabutylammonium

  已经研究了在各种条件下的2，3-二芳基环戊-2-烯-1-酮的溴化。已经发现，取决于溴化试剂和溶剂的性质，可以将溴原子引入乙烯“桥”的4-或5-位以及芳基部分。芳基溴化是通过诸如分子溴，N-溴琥珀酰亚胺或四丁基三溴化铵之类的试剂完成的。与溴化铜（II）在甲醇中反应可制得效率极高的5-溴环戊烯酮，而n则可制得4-溴酮。乙酸丙酯。所开发的方法对于合成在有机合成中重要的合成子的溴取代的2-环戊烯-1-酮及其紧密类似物可能非常有用，并用于制备各种有用的物质。

  A selective, reductive, deoxygenation of 2-aryl-4-hydroxycyclopent-2-en-1-ones to afford 2-aryl-cyclopent-2-en-1-ones was achieved by NaBH4–CeCl3 in methanol.
