  Anodic Oxidation of Unsaturated Aliphatic Ethers in aqueous electrolytes

  摘要：

  2,5-dihydrofuran 1 was galvanostatically oxidized in aqueous electrolytes on Pt and PbO2 anodes at current densities of 10 to 50 mA cm(-2). Under acidic conditions maleic dialdehyde 2 was obtained on bath electrodes with a current efficiency (c.e.) of up to 50%. In the alkaline region (pH 10) 4-hydroxy crotonic aldehyde 3 (Pt) or 2,5-dihydrofuranone 4 (PbO2) become the main products with c.e.'s of 29% and 27%, respectively, depending on the anode material. The influence of pH and of the anode material are discussed in detail. 2,3-dihydrofuran 7, vinyl ethyl ether 8 and for comparison, furan 9 were studied in addition.

• Atmospheric chemistry of benzene oxide/oxepin
  作者：Björn Klotz、Ian Barnes、Karl H. Becker、Bernard T. Golding

  DOI：10.1039/a606152d

  日期：——

  The atmospheric chemistry of benzene oxide/oxepin, a possible intermediate in the atmospheric oxidation of aromatic hydrocarbons, has been investigated in a large volume photoreactor at 298 K and atmospheric pressure using in situ FTIR spectroscopy for the analysis. Rate coefficients of (10.0±0.4)×10 -11 and (9.2±0.3)×10 -12 cm 3 molecule -1 s -1 have been determined for the reaction of benzene oxide/oxepin with OH and NO 3 radicals, respectively. Reaction with OH radicals produces almost exclusively the (E,Z)- and (E,E)-isomers of hexa-2,4-dienedial, whereas reaction with NO 3 produces (Z,Z)-hexa-2,4-dienedial and unidentified organic nitrates. Phenol has been observed as a major product of the thermal decomposition, visible and UV photolysis of benzene oxide/oxepin. The results are discussed in conjunction with the oxidation mechanisms of aromatic hydrocarbons. The major atmospheric sinks of benzene oxide/oxepin will be reaction with OH radicals and photolysis and, under smog chamber conditions with high NO 2 concentrations, also reaction with NO 3 .

  The gas-phase reaction of OH radicals with benzene was studied in O2/He mixtures under flow conditions in the temperature range 276–353 K and at pressures of 100 and 500 mbar using on-line FT-IR spectroscopy and GC-MS measurements. The reaction conditions were chosen so that the initially formed OH/benzene adduct predominantly reacted either with O2 or O3. Under conditions of a predominant reaction

Reduction of the resulting tropene by use of SmI(2) or by catalytic hydrogenation followed by deprotection delivered the final target compounds. Some of these compounds were found to retain considerable affinity as inhibitors of the dopamine transporter

  在我们努力确定可能充当可卡因拮抗剂或可卡因部分激动剂的分子的过程中，人们努力利用我们先前关于7-甲氧基化拟可卡因类似物作为弱可卡因功能拮抗剂的能力的发现。本文中，制备了一系列具有环烷环的船形或椅子构型的6-和7-羟基化WIN类似物，并测试了它们取代[（3H）] mazindol结合并抑制高亲和力单胺摄取的能力。大鼠脑神经末梢。这些6和7羟基化的WIN类似物很容易通过经典的Willstätter合成来构建适当官能化的tropane环，然后使用Suzuki偶联反应在3位引入芳基来制备。通过使用SmI（2）或催化氢化，再进行脱保护反应，还原所得的托品，得到最终的目标化合物。发现这些化合物中的某些保留作为多巴胺转运蛋白（DAT）和去甲肾上腺素转运蛋白（NET）的抑制剂具有相当大的亲和力，但它们不是血清素转运蛋白（SERT）的有效抑制剂。本系列化合物均未显示[（3）H] mazindol结合与[（3）H]
• Comparative Metabolism of Furan in Rodent and Human Cryopreserved Hepatocytes

  Furan is a liver toxicant and carcinogen in rodents. Although humans are most likely exposed to furan through a variety of sources, the effect of furan exposure on human health is still unknown. In rodents, furan requires metabolism to exert its toxic effects. The initial product of the cytochrome P450 2E1-catalyzed oxidation is a reactive α , β -unsaturated dialdehyde, cis -2-butene-1,4-dial (BDA). BDA is toxic and mutagenic and consequently is considered responsible for the toxic effects of furan. The urinary metabolites of furan in rats are derived from the reaction of BDA with cellular nucleophiles, and precursors to these metabolites are detected in furan-exposed hepatocytes. Many of these precursors are 2-( S -glutathionyl)butanedial-amine cross-links in which the amines are amino acids and polyamines. Because these metabolites are derived from the reaction of BDA with cellular nucleophiles, their levels are a measure of the internal dose of this reactive metabolite. To compare the ability of human hepatocytes to convert furan to the same metabolites as rodent hepatocytes, furan was incubated with cryopreserved human and rodent hepatocytes. A semiquantitative liquid chromatography with tandem mass spectrometry assay was developed for a number of the previously characterized furan metabolites. Qualitative and semiquantitative analysis of the metabolites demonstrated that furan is metabolized in a similar manner in all three species. These results indicate that humans may be susceptible to the toxic effects of furan.

  呋喃在啮齿动物中是一种肝毒物和致癌物。尽管人类很可能通过多种途径接触到呋喃，但呋喃暴露对人类健康的影响尚不清楚。在啮齿动物中，呋喃需要经过代谢才能发挥其毒性作用。细胞色素P450 2E1催化的氧化作用的初始产物是一种活性α,β-不饱和二醛，即顺-2-丁烯-1,4-二醛（BDA）。BDA具有毒性和诱变性，因此被认为是导致呋喃毒性效应的原因。大鼠尿液中的呋喃代谢物来源于BDA与细胞亲核体的反应，这些代谢物的前体在呋喃暴露的肝细胞中被检测到。许多这些前体是2-(S-谷胱甘肽基)丁二醛-胺交联物，其中的胺是氨基酸和多胺。由于这些代谢物来源于BDA与细胞亲核体的反应，它们的水平可以作为这种活性代谢物内部剂量的衡量标准。为了比较人肝细胞与啮齿动物肝细胞将呋喃转化为相同代谢物的能力，将呋喃与冷冻保存的人和啮齿动物肝细胞一起孵育。开发了一种半定量的液相色谱-串联质谱法，用于检测先前鉴定的一些呋喃代谢物。对这些代谢物的定性和半定量分析表明，呋喃在所有三种物种中以类似方式被代谢。这些结果表明，人类可能对呋喃的毒性作用敏感。
