  摘要：

  对称的乙烯基二噻吩是光致变色材料和有机导体合成的重要中间体。当使用乙腈作为溶剂时，3-甲基硫代苯基phosph盐在强碱（例如NaH，（t）BuOK）存在下以中等至高收率形成对称的乙烯基二噻吩。该均偶联反应比与乙腈中的芳族酮的维蒂希反应更快。我们的研究表明，极性非质子溶剂的存在会促进均偶联反应。

• A Convenient Synthesis of Symmetric 1,2-Diarylethenes from Arylmethyl Phosphonium Salts

  日期：2006.8.1

  Symmetric ethenyldithiophenes are important intermediates for synthesis of photochromic materials and organic conductors. When acetonitrile is used as a solvent, 3-methylthiophenylphosphonium salts form symmetric ethenyldithiophenes in the presence of a strong base (e.g., NaH, (t)BuOK) in moderate to high yields. This homocoupling reaction is faster than a Wittig reaction with aromatic ketones in acetonitrile

• Alkylatlon orientation rules in conjugate addition of grignard reagents to nitropyrrole and nitrothiophene systems
  作者：Roberto Ballini、Giuseppe Bartoli、Marcella Bosco、Renato Dalpozzo、Enrico Marcantoni

  日期：——

  Conjugate addition of various Grignard reagents to 1-alkyl-2-nitropyrroles and to 2-nitrothiophene has been investigated. 1-Alkyl-2-nitropyrroles undergo alkylation at 3 and 5 positions with prevalence of the latter isomer. On the contrary, in 2-nitrothiophene system, formation of the 3-isomer prevails. In both systems, a bulkier Grignard reagent favours the 5-isomer formation. This trend can be reversed

  已经研究了将各种格氏试剂偶联到1-烷基-2-硝基吡咯和2-硝基噻吩上的方法。1-烷基-2-硝基吡咯在3和5位发生烷基化，后一种异构体普遍存在。相反，在2-硝基噻吩系统中，形成了3-异构体。在两种体系中，较大的格利雅试剂都有利于5-异构体的形成。这种趋势可以逆转，由2-硝基吡咯的1-取代基增加空间位阻。1-（三异丙基甲硅烷基）-3-硝基吡咯和3-硝基噻吩仅产生2-异构体。该反应允许通过一锅法而不是经典的多阶段反应来合成2-烷基-3-硝基噻吩和吡咯。

• Synthesis of a series of nitrothiophenes with basic or electrophilic substituents and evaluation as radiosensitizers and as bioreductively activated cytotoxins

  A series of 2- and 3-nitrothiophene-5-carboxamides bearing N-(omega-aminoalkyl) side chains has been prepared by treatment of the thiophenecarbonyl chloride with the appropriate (protected) omega-aminoalkylamine. Analogous N-(oxiranylmethyl)nitrothiophene-5-carboxamides have been synthesized by epoxidation of the corresponding N-allylamide. Compounds in both classes were evaluated in vitro both as radiosensitizers of hypoxic mammalian cells and as selective bioreductively activated cytotoxins. The most potent radiosensitizers were those agents with strong tertiary amine bases or oxiranes in the side chain. Studies in vivo showed that 2-methyl-N-[2-(dimethylamino)ethyl]-3-nitrothiophene-5-carboxamide caused slight radiosensitization of the KHT sarcoma in mice given 0.34 mmol kg-1. However, administration of this and related tertiary amines at higher doses was precluded by systemic toxicity.
