  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。

  series of alpha,alpha-difluorobenzylphosphonic acids having a hydrophobic functional group were prepared via the Stille coupling reaction from halogenated alpha,alpha-difluorobenzylphosphonates. Evaluation of inhibitory activity toward protein tyrosine phosphatase (PTP 1B) revealed that the ethynyl, phenylethynyl and (E)-styryl groups on the benzene nuclei increased the inhibitory activity of alpha,alph

  通过Stille偶联反应，由卤化的α，α-二氟苄基膦酸酯制备了一系列具有疏水性官能团的α，α-二氟苄基膦酸。对蛋白酪氨酸磷酸酶（PTP 1B）的抑制活性的评估表明，苯核上的乙炔基，苯基乙炔基和（E）-苯乙烯基增加了α，α-二氟苄基膦酸的抑制活性。将（E）-苯乙烯基和双甲基磺酰胺官能团同时引入到α，α-二氟苄基膦酸的苯核上时，抑制活性显着提高。

  The copper-catalysed zinc phosphonate chemistry described by Yokomatsu and Shibuya can be used directly in the synthesis of phosphotyrosine analogue F(2)Pmp, and in entering the classical organometallic coupling repertoire via Stille and Suzuki-Miyaura couplings. Herein, we report a streamlined synthesis of F(2)Pmp, and of a pivotal triflate, which undergoes a range of palladium-catalysed couplings with aryl and heteroaryl components.

  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.
