  • Stereoselective Isoxazolidine Synthesis Via Copper-Catalyzed Alkene Aminooxygenation

    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

    isoxazolidines with moderate cis-selectivity (up to 7: 1). Electrophilic cyclisation of N-acylated O-homoallyl hydroxylamines provides isoxazolines or isoxazolidines depending on the reaction conditions (reagents). The t-BuOCl-mediated cyclisation affords isoxazolines via an oxidative cyclisation, whereas the NIS-induced reaction provides the 5-exo-cyclisation product with high stereoselectivity (cis:trans =
    讨论了各种 O-高烯丙基羟胺衍生物的亲电环化。未受保护的 O-高烯丙基羟胺经历氧化环化为异恶唑啉。新的异恶唑啉合成包括初始亲电环化以形成中间体异恶唑烷,随后将其氧化成异恶唑啉。可以用各种亲电子试剂(t-BuOCl、PhSeBr、NBS 和 NIS)进行环化。如果起始 O-高烯丙基羟胺是 N-磺酰化的,则可以抑制氧化。然后亲电环化提供具有中等顺式选择性(高达 7:1)的 N-磺酰化异恶唑烷。N-酰化的 O-高烯丙基羟胺的亲电环化根据反应条件(试剂)提供异恶唑啉或异恶唑烷。
  • Influence of Hydroxylamine Conformation on Stereocontrol in Pd-Catalyzed Isoxazolidine-Forming Reactions
    作者:Georgia S. Lemen、Natalie C. Giampietro、Michael B. Hay、John P. Wolfe
    DOI:10.1021/jo8027399
    日期:2009.3.20
    Palladium-catalyzed carboamination reactions between N-Boc-O-(but-3-enyl)hydroxylamine derivatives and aryl or alkenyl bromides afford cis-3,5- and trans-4,5-disubstituted isoxazolidines in good yield with up to >20:1 dr. The diastercoselectivity observed in the formation of cis-3,5-disubstituted isoxazolidines is superior to selectivities typically obtained in other transformations, such as 1,3-dipolar cycloaddition reactions, that provide these products. In addition, the stereocontrol in the C-N bond-forming Pd-catalyzed carboamination reactions of N-Boc-O-(but-3-enyl)hydroxylamines is significantly higher than that of related C-O bond-forming carboetherification reactions of N-benzyl-N-(but-3-enyl)hydroxylamine derivatives. This is likely due to a stereoelectronic preference for cyclization via transition states in which the Boc group is placed in a perpendicular orientation relative to the plane of the developing ring, which derives from the conformational equilibria of substituted hydroxylamines.

  • Palladium/norbornene-catalyzed distal alkenyl C–H arylation and alkylation of cis-olefins
    作者:Zhao Wu、Nina Fatuzzo、Guangbin Dong
    DOI:10.1016/j.tet.2021.132173
    日期:2021.6
    In this full article, a detailed study of a distal alkenyl C–H arylation and alkylation through the palladium/norbornene (NBE) cooperative catalysis is described. Both aminopyridine- and oxime ether-type directing groups have been found effective for this transformation, allowing functionalization of diverse allyl amines and homoallyl alcohols. In addition, the C5,C6-substititued NBEs show optimal
