  Copper-Catalyzed N-Allenylation of Allylic Sulfonamides

  摘要：

  Allylic allenic amides have been synthesized via a copper-catalyzed cross-coupling between allylic sulfonamides and bromoallenes in moderate to good yields. Copper(I) thiophene-2-carboxylate (CuTC) was used a source of copper with DMEDA as the ligand. The allenylated products obtained are potential substrates for palladium-catalyzed carbocyclizations.

• Copper‐Catalyzed Azide–Ynamide Cyclization to Generate α‐Imino Copper Carbenes: Divergent and Enantioselective Access to Polycyclic N‐Heterocycles
  作者：Xin Liu、Ze‐Shu Wang、Tong‐Yi Zhai、Chen Luo、Yi‐Ping Zhang、Yang‐Bo Chen、Chao Deng、Rai‐Shung Liu、Long‐Wu Ye

  Here an efficient copper‐catalyzed cascade cyclization of azide‐ynamides via α‐imino copper carbene intermediates is reported, representing the first generation of α‐imino copper carbenes from alkynes. This protocol enables the practical and divergent synthesis of an array of polycyclic N‐heterocycles in generally good to excellent yields with broad substrate scope and excellent diastereoselectivities

  在此报道了通过α-亚氨基铜卡宾中间体对叠氮化物-酰胺类进行有效的铜催化级联环化反应，代表了炔烃的第一代α-亚氨基铜碳烯。该协议使多环N-杂环阵列的实用和发散性合成具有良好的收率，具有广泛的底物范围和出色的非对映选择性，通常具有良好的产率。此外，通过使用BOX-Cu络合物作为手性催化剂，已经实现了具有高对映选择性（高达98：2 er）的不对称叠氮化物-酰胺酰胺环化反应。因此，该协议构成了不对称叠氮化物-炔烃环化的第一个例子。理论计算进一步支持了该级联环化的机理原理。

  Asymmetric epoxidation of allylic and homoallylic amine derivatives catalyzed by Hf(IV)-bishydroxamic acid complexes is described. Under similar conditions, aldimine and ketimine produced oxaziridines. The sulfonyl group is demonstrated to be an effective directing group for these transformations.

  Enantioselective syntheses of bicyclic cyclopentenones are described. Key steps are an iridium-catalyzed allylic substitution and an intramolecular diastereoselective Pauson–Khand reaction. The diastereoselectivity of the Pauson–Khand reaction was found to be crucially dependent on the unit connecting the propargylic and the olefinic parts of the precursor. Very high degrees of diastereoselection were

  描述了双环环戊烯酮的对映选择性合成。关键步骤是铱催化的烯丙基取代和分子内非对映选择性的Pauson-Khand反应。发现鲍森-汉德反应的非对映选择性主要取决于连接前体的炔丙基和烯烃部分的单元。使用NBoc单元作为连接器可获得非常高的非定向变形度。通过在（-）-α-海藻酸的对映选择性正式全合成中的应用说明了该方法。
