  Synthesis of 3-iodothiophenes via iodocyclization of (Z)-thiobutenynes

  摘要：

  A simple synthesis of 3-iodothiophenes was demonstrated using a wide range of (Z)-thioenynes. The key step in the iodocyclofunctionalization was the selective reduction of the triple bond in (Z)-thioenynes by the addition of iodine as an electrophilic agent. The 3-iodothiophenes were obtained in good to excellent yields of 61-92%. The 3-iodothiophenes were used as substrates in Sonogashira cross-coupling reactions to obtain thiophene acetylenes.

  通过形式的硫代硼酸酯无过渡金属合成的硼化的噻吩

  摘要：

  据报道，一种简单的，不受区域控制的，无过渡金属的方法仅可访问3-硼化的噻吩衍生物。市售的B-氯邻苯二甲硼烷试剂（ClBcat）用作亲碳的路易斯酸，以活化易于合成的（Z）-有机基硫代炔炔底物中的炔烃。硼诱导的活化引发了正式的硫代硼化和随后的硫脱烷基化，从而以高收率形成了3-硼化的噻吩。所得的硼化噻吩可分离为硼酸酯（Bpin）和硼酰胺（Bdan）。这些硼化的产物适合于各种下游官能化反应，即通过交叉偶联，叠氮化，溴化和CH活化形成CC键。

  Hydrothiolation of 1-organylbuta-1,3-diynes and 1,4-diorganylbuta-1,3-diynes with the sodium organylthiolate anions, which were generated in situ by reacting diphenyl and dibutyl di­sulfide with NaBH4 in ethanol, results in the regio-, stereo-, and chemoselective formation of (Z)-1-organylthio-4-organylbut-1-en-3-ynes and (Z)-1-organylthio-1,4-diorganylbut-1-en-3-ynes, respectively.

  We present our results on the cyclization of (Z)-chalcogenoenynes mediated by copper(II) salts to afford 3-halochalcogenophenes in satisfactory yields through an intramolecular 5-endo-dig cyclization. The methodology was carried out using CuCl2 at 50 °C or CuBr2 at room temperature under an ambient atmosphere. The reaction took place under very mild reaction conditions and tolerated considerable functionality

  我们展示了由铜 (II) 盐介导的 (Z)-硫属元素烯环化的结果，通过分子内 5-endo-dig 环化以令人满意的产率提供 3-卤代硫属元素烯。该方法是在 50 °C 下使用 CuCl2 或在室温下在环境气氛下使用 CuBr2 进行的。该反应在非常温和的反应条件下进行并且耐受相当大的官能度。在钯催化的与硼酸的交叉偶联反应中，将一种 3-溴-硒吩衍生物用作底物，以良好的收率得到 Suzuki 型产物。

  Hydrothiolation of symmetrical and unsymmetrical buta-1,3-diynes with sodium organylthiolate anions in reflux, generated in situ by reacting C4H9SH with NaOH, afforded (Z)-organylthioenynes in low to good yields (25-80%). By using tetrabutylammonium hydroxide (TBAOH) as base instead of NaOH, the hydrothiolation of buta-1,3-diynes was more rapid and efficient, providing (Z)-organylthioenynes in good to excellent yields (70-95%).

  exclusively 3-borylated thiophene derivatives is reported. The commercially available B-chlorocatecholborane reagent (ClBcat) acts as a carbophilic Lewis acid to activate the alkyne in readily synthesized (Z)-organylthioenyne substrates. This boron-induced activation initiates the formal thioboration and subsequent sulfur dealkylation, leading to the formation of 3-borylated thiophenes in good yields. The
