• Titanium and Cobalt Bimetallic Radical Redox Relay for the Isomerization of N-Bz Aziridines to Allylic Amides

  日期：2021.11

  Herein a bimetallic radical redox-relay strategy is employed to generate alkyl radicals under mild conditions with titanium(III) catalysis and terminated via hydrogen atom transfer with cobalt(II) catalysis to enact base-free isomerizations of N-Bz aziridines to N-Bz allylic amides. This reaction provides an alternative strategy for the synthesis of allylic amides from alkenes via a three-step sequence

  本文采用双金属自由基氧化还原-中继策略，在钛(III)催化的温和条件下生成烷基自由基，并通过钴(II)催化的氢原子转移终止，以进行N -Bz氮丙啶到N -Bz的无碱异构化烯丙基酰胺。该反应提供了一种通过三步序列从烯烃合成烯丙基酰胺的替代策略，以完成正式的转位烯丙基胺化。

  An amino-indanol derived chiral guanidine was developed as an efficient Brønsted base catalyst for the desymmetrization of meso-aziridines with both thiols and carbamodithioic acids as nucleophiles, which provided 1,2-difunctionalized ring-opened products in high yields and enantioselectivities.

  Conditions for the phosphoric acid-catalyzed highly enantioselective ring-opening of meso-aziridines with a series of functionalized aromatic thiol nucleophiles are described. The procedure utilizes commercially available aromatic thiols, a series of meso-aziridines, and a catalytic amount of VAPOL phosphoric acid to explore the substrate scope of this highly enantioselective reaction.
• Studies on the true catalyst in the phosphate-promoted desymmetrization of meso-aziridines with silylated nucleophiles

  Significant amounts of metal phosphate impurities have been detected by NMR spectroscopy and ICP-OES analysis of synthetic, as well as purchased, samples of VAPOL hydrogen phosphate purified on silica gel. The previously reported VAPOL hydrogen phosphate-catalyzed desymmetrization of meso-aziridines with different silylated compounds, has been re-examined. While metal-free phosphoric acid exhibited low activity and enantioselectivity, calcium and magnesium phosphate salts proved to be the true catalysts in these related processes. Reproducible high enantioselectivities were obtained in the ring-opening of cyclic meso-aziridines with Me3SiX (X=SPh, SePh, N-3) employing a 1:1 mixture of calcium and magnesium VAPOL phosphates. The reaction has been successfully extended to Me3SiSBn, Me3SiSMe and Me3SiNCS, giving ring-opened products in high yield and unprecedented moderate to good enantioselectivities.
