  Total Synthesis of (±)-Martinellic Acid

  摘要：

  [GRAPHICS]A 14-step synthesis of martinellic acid (1) that proceeds in 3% overall yield has been completed using the reaction of aniline 11 with Meldrum's acid-activated vinylcyclopropane 4 to give vinyl pyrrolidinone 12, condensation of aldehyde 13 with N-benzylglycine to form an azomethine ylide that cyclizes to give 14, selective reduction of 14 to amino alcohol 16 with LiBH4 and MeOH, and guanidine formation by reaction of a cyanamide with 3-methyl-2-buten-1-amine in hexafluoro-2-propanol at 120 degreesC as key steps,

  Switching reaction pathways of trifluoromethylated thiobenzanilides by choice of different oxidative systems

  摘要：

  Trifluoromethylated thiobenzanilides are efficiently converted to 2-trifluoromethylbenzothiazoles via intramolecular oxidative cyclization under CAN/NaHCO(3) oxidation, while the dimerized products with "-S-S-" bond linkage are obtained when PIDA is used as an oxidant.

  report the first example of a Cu-catalyzed trifluoromethylation reaction in which a ligand controls the regiochemical outcome. More specifically, we demonstrate the ability of bipyridyl-derived ligands to control the regioselectivity of the Cu-catalyzed nucleophilic trifluoromethylation reactions of propargyl electrophiles to generate (trifluoromethyl)allenes. This method provides a variety of di-

  历史上，“ Cu–CF 3 ”物种已用于广泛的亲核三氟甲基化反应。尽管最近的进展已经使用了配体来稳定和利用这一关键有机金属中间体的反应性，但是配体区分Cu–CF 3的区域化学结果的能力以前尚未报道过介导或催化的反应。在此，我们报道了一个铜催化的三氟甲基化反应的第一个例子，其中配体控制了区域化学结果。更具体地说，我们证明了联吡啶基配体控制铜催化的炔丙基亲电子的亲核三氟甲基化反应生成（三氟甲基）丙二烯的区域选择性的能力。该方法提供了各种二，三和四取代的（三氟甲基）亚芳基，可以对其进行进一步修饰以生成复杂的氟化亚结构。

  A catalytic method was developed to synthesize primary arylamines from the corresponding aryl bromides and iodides under mild conditions (yields = 80–99%). Crystalline 2,2,2-trifluoroacetamide was used as ammonia surrogate and CuI/N,N′-dimethyl ethylenediamine was used as catalyst to achieve the C–N cross-coupling.

  An electrostatically directed meta borylation of sterically biased and unbiased substrates is described. The borylation follows an electrostatic interaction between the partially positive and negative charges between the ligand and substrate. With this strategy, it has been demonstrated that a wide number of challenging substrates, especially 4-substituted substrates, can selectively be borylated at

  描述了空间偏压和无偏压底物的静电定向代谢硼化。硼酸化遵循配体和底物之间部分正电荷和负电荷之间的静电相互作用。使用这种策略，已经证明大量具有挑战性的底物，尤其是 4 取代底物，可以在间位选择性地硼酸化。此外，未取代的底物也表现出优异的间位选择性。该反应采用实验室稳定的配体并在较温和的温度下进行，无需合成庞大而复杂的配体/模板。

  The development and optimization of a palladium-catalyzed asymmetric conjugate addition of arylboronic acids to cyclic enone conjugate acceptors is described. These reactions employ air-stable and readily-available reagents in an operationally simple and robust transformation that yields β-quaternary ketones in high yields and enantioselectivities. Notably, the reaction itself is highly tolerant of

  描述了钯催化芳基硼酸与环烯酮共轭受体的不对称共轭加成的开发和优化。这些反应采用空气稳定且易于获得的试剂，通过操作简单且稳健的转化，以高产率和对映选择性产生 β-季酮。值得注意的是，反应本身对大气中的氧气和湿气具有高度耐受性，因此不需要使用干燥或脱氧溶剂、特别纯化的试剂或惰性气氛。烯酮的环大小和β-取代基变化很大，可以合成多种β-季酮。最近，NH 4 PF 6的使用进一步扩大了底物范围，包括含杂原子的芳基硼酸和β-酰基烯酮底物。
