  摘要：

  横松和渋谷描述的铜催化锌膦酸酯化学可用于通过斯蒂尔（Stille）和铃木-宫浦（Suzuki-Miyaura）偶联反应进入经典的金属有机偶联反应领域。1,4-二碘苯在铜(I)催化下与由二乙基溴二氟甲基膦酸酯衍生的有机锌试剂发生偶联，生成二乙基(4-碘苯基)二氟甲基膦酸酯。与(4-三氟甲磺酰氧基)和(4-九氟丁磺酰氧基)碘苯进行的偶联反应产率更高。碘化物和三氟甲磺酸酯在钯催化条件下与一系列锡烷和硼酸发生偶联，产率从中等到优异。渋谷-横松偶联反应在具有更丰富官能团的碘芳烃和杂芳烃上也取得了成功，这些重要磷酸类似物被引入多种骨架上。

  The copper-catalysed zinc phosphonate chemistry described by Yokomatsu and Shibuya can be used to enter the classical organometallic coupling repertoire via Stille and Suzuki–Miyaura couplings. 1,4-Diiodobenzene underwent coupling with the organozinc reagent derived from diethyl bromodifluoromethylphosphonate with copper(I) catalysis to afford diethyl (4-iodophenyl)difluoromethylphosphonate. Higher yielding couplings were run with (4-trifluoromethylsulfonyloxy)- and (4-nonafluorobutylsulfonyloxy)-iodobenzenes. The iodide and the triflate coupled under palladium-catalysed conditions with a range of stannanes and boronic acids in moderate to excellent yields. Shibuya–Yokomatsu couplings were also successful with more functionalised iodoarenes and heteroarenes presenting the important phosphate mimic on a range of scaffolds.

  The current Letter describes the synthesis and biological evaluation of dihydrophthalazine-appended 2,4-diaminopyrimidine (DAP) inhibitors (1) oxidized at the methylene bridge linking the DAP ring to the central aromatic ring and (2) modified at the central ring ether groups. Structures 4a–b incorporating an oxidized methylene bridge showed a decrease in activity, while slightly larger alkyl groups

• The Taming of Capsaicin. Reversal of the Vanilloid Activity of <i>N</i>-Acylvanillamines by Aromatic Iodination

  Aromatic iodination ortho to the phenolic hydroxyl reverts the activity of the ultrapotent vanilloid agonist resiniferatoxin (RTX, 1a), generating the ultrapotent antagonist 5'-iodoRTX (1b). To better understand the role of iodine in this remarkable switch of activity, a systematic investigation on the halogenation of vanillamides, a class of compounds structurally simpler than resiniferonoids, was carried out. The results showed that (a) the antagonistic activity depends on the site of halogenation and is maximal at C-6', (b) iodine is more efficient than chlorine and bromine at reverting the agonistic activity, and (c) iodine-carbon exchange decreases antagonist activity. Iodine-induced reversal of vanilloid activity was also observed in vanillamides more powerful than capsaicin, but a poor correlation was found between agonistic and antagonistic potencies, suggesting that differences exist in the way vanillamides and their 6'-iodo derivatives bind to TRPV1".
