  铁使能利用空气作为终端氧化剂，导致有机硒催化的好氧氧化脱氧

  摘要：

  与需要过氧化物氧化剂（例如过氧化氢）的常规有机硒催化氧化反应相反，在这项工作中，我们发现，添加低含量的铁（II）可以使空气成功地用作有机硒催化的末端氧化剂酮肟的氧化脱氧反应。这导致了一种新的温和且相对绿色的好氧氧化脱氧方法。控制反应和X射线光电子能谱（XPS）分析表明，铁在催化循环中至关重要，它通过空气将低价硒物种通过铁催化有氧氧化为活性高价硒而阻止硒催化剂失活。物种。由于可以将空气用作末端氧化剂，因此这项工作可能有助于有机硒催化的发展。

  A highly effective quenching method of 1,3-dipolar cycloadditions of nitrile oxides or nitrile oxide/Lewis acid complexes by use of 2-propenyloxymagnesium bromide

  摘要：

  2-Propenyloxymagnesium bromide, readily prepared by treating 2-propen-1-ol with EtMgBr, is a highly effective quencher of nitrile oxide cycloadditions since this alkoxide is much more reactive to nitrile oxides than any other ever known dipolarophiles of the electron-deficient, electron-rich, and strained types, including 3-buten-2-one, ethyl vinyl ether, and norbornene, respectively. This quencher is also effectively utilized to terminate the dipolar cycloadditions of nitrile oxide/Lewis acid complexes.

  salicyloxazoline based oxorhenium(V) complexes have been synthesized and their catalytic application for the asymmetric reduction of ketimines using hydrosilane as hydride source is disclosed. A broad substrate scope, high yields, and excellent enantioselectivities (up to 99 %) are attained. Furthermore, the syntheses of enantiopure α‐amino esters, γ‐ and δ‐lactams, and isoindolinones have also been carried

  The N,N′-dioxide−Cu(OTf)2 complexes were applied in the asymmetric amination reaction of N-acetyl enamides with dialkyl azodicarboxylate, giving the corresponding products in good yields with high enantioselectivities (up to 91% ee). Precursors of vicinal diamine were readily obtained with excellent diastereoselectivities (>95:5) by NaBH4 reduction.
