  Electroorganic Chemistry. 144. Electroreductive Coupling of Ketones with O-Methyl Oximes, N,N-Dimethylhydrazones, and Nitrones. A Convenient Route to Synthesis of .beta.-Amino Alcohol

  摘要：

  The intermolecular coupling of a variety of ketones with some types of O-methyl oximes took place when a mixture of both components was electrochemically reduced in i-PrOH with an Sn cathode. The product, beta-methoxyamino alcohol was easily converted to beta-amino alcohol by simple reduction. A chiral ligand effective for the enantioselective addition of diethylzinc to an aldehyde was easily obtained from the product formed by the electroreductive coupling of (-)-menthone with O-methylacetaldoxime. The intermolecular coupling of a ketone with a N,N-dimethylhydrazone or nitrone was also promoted by the electroreduction. Furthermore, the electroreductive coupling of a carbonyl group with an intramolecular O-methyl oxime moiety gave the corresponding cyclized product stereoselectively.

  (C6F5N+H3⋅NTf2−) promotes Mukaiyama aldol and Mannich reactions using ketene silyl acetals with ketones and oxime ethers, respectively. The present robust method is mild, but powerful enough to utilize less accessible electrophiles such as enolizable ketones and oxime ethers to produce a variety of β‐hydroxy esters and β‐alkoxyamino esters, respectively. Mechanistic investigation revealed in situ generation

  A highly efficient and stereoselective synthesis of enantioenriched imidazolidines by rhodium-catalyzed intermolecular [3 + 2] cycloaddition reaction of chiral vinyl aziridines and oxime ethers has been successfully developed. Notably, both aldoximes and ketoximes are suitable substrates to afford the corresponding chiral imidazolidines in high yields with good stereoselectivity. This transformation

  Here, we report an efficient and modular approach toward the formation of difluorinated arylethylamines from simple aldehyde-derived N,N-dialkylhydrazones and trifluoromethylarenes (CF3-arenes). This method relies on selective C–F bond cleavage via reduction of the CF3-arene. We show that a diverse set of CF3-arenes and CF3-heteroarenes react smoothly with a range of aryl and alkyl hydrazones. The β-difluorobenzylic

  在这里，我们报告了一种从简单的醛衍生N,N -二烷基腙和三氟甲基芳烃 (CF 3 -芳烃)形成二氟化芳基乙胺的有效模块化方法。该方法依赖于通过 CF 3 -芳烃的还原选择性 C-F 键断裂。我们表明，一组不同的 CF 3 -芳烃和 CF 3 -杂芳烃与一系列芳基和烷基腙顺利反应。β-二氟苄基肼产物可以选择性地裂解形成相应的苄基二氟芳基乙胺。
