  Oxidative Intramolecular Bromo-Amination of N-Alkenyl Sulfonamides via Umpolung of Alkali Metal Bromides

  摘要：

  The oxidative intramolecular bromo-amination of various N-alkenyl sulfonamides and N-alkenoxyl sulfonamides via umpolung of alkali metal bromides occurred exo-selectively to generate cyclic bromoamides in high yields with good diastereoselectivities. This method provided the desired products without elaborating the stoichiometric amount of corresponding organic waste.

  Isoxazolidines are useful in organic synthesis, drug discovery, and chemical biology endeavors. A new stereoselective synthesis of methyleneoxy-substituted isoxazolidines is disclosed. The method involves copper-catalyzed aminooxygenation/cyclization of N-sulfonyl-O-butenyl hydroxylamines in the presence of (2,2,6,6-tetramethylpiperidin-1-yl)oxyl radical (TEMPO) and O2 and provides substituted isoxazolidines

  异恶唑烷可用于有机合成、药物发现和化学生物学研究。公开了亚甲氧基取代的异恶唑烷的新立体选择性合成。该方法包括在 (2,2,6,6-四甲基哌啶-1-基)氧基自由基 (TEMPO) 和 O 2存在下铜催化的N-磺酰基-O-丁烯基羟胺的氨基氧化/环化，并提供取代的异恶唑烷优异的产率和非对映选择性。我们还展示了选择性单 N-O 还原，然后氧化剩余的 N-O 键以显示 2-氨基-γ-内酯。γ-内酯的还原揭示了相应的氨基二醇。

  A convenient copper-catalyzed intramolecular/intermolecular alkene diamination reaction to synthesize 3-aminomethyl-functionalized isoxazolidines under mild reaction conditions and with generally high levels of diastereoselectivity was achieved. This reaction demonstrates that previously underutilized unsaturated carbamates are good [Cu]-catalyzed diamination substrates. Sulfonamides, anilines, benzamide

  实现了一种方便的铜催化的分子内/分子间烯烃缩氨基反应，该反应可在温和的反应条件下且通常具有较高的非对映选择性地合成3-氨基甲基官能化的异恶唑烷。该反应表明，先前未充分利用的不饱和氨基甲酸酯是良好的[Cu]催化的金属化底物。磺酰胺，苯胺，苯甲酰胺，吗啉和哌啶可以用作外部胺源。该相对较宽的胺范围归因于温和的反应条件。还可以减少N–O键，从而有效地揭示相应的3,4-二氨基-1-醇。

  A time-economical and robust synthesis of various selenofunctionalized heterocycles was accomplished via I2O5-mediated selenocyclizations of olefins with diselenides. Using this method, 116 selenomethyl-substituted heterocycles were synthesized with up to 97% isolated yield in minutes. Additional features of this new protocol include the use of an inorganic oxidant, mild conditions, and easy operation

  日期：2018.6.1

  The first example of a Pd(OAc)(2)-catalyzed ring-forming alkene aminoaroylation of unsaturated hydrazones and sulfonamides is described. This protocol features the use of diaryliodonium salts as both oxidants and aryl sources, thus enabling mild reaction conditions, good chemoselectivity, a broad substrate scope, and high functional group tolerance. A wide range of synthetically and biologically important functionalized dihydropyrazoles and isoxazolidines have been obtained in good yields.
