  • Efficient Synthesis of <i>N-</i>Alkylated α,β-Unsaturated Ketonitrones via Cu-Catalyzed Rearrangement
    作者:Itaru Nakamura、Toshiki Onuma、Ryo Kanazawa、Yuki Nishigai、Masahiro Terada
    DOI:10.1021/ol501889g
    日期:2014.8.15
    N-Alkylated unsaturated ketonitrones were efficiently synthesized from propargyloxyamines using Cu catalysts. Mechanistic studies suggest that the rearrangement reaction proceeds via Cu-catalyzed intramolecular hydroamination, followed by thermally induced electrocyclic ring opening.
    使用铜催化剂从炔丙基氧胺有效地合成了N-烷基化的不饱和酮硝基。机理研究表明,重排反应是通过Cu催化的分子内加氢胺化反应进行的,随后是热诱导的电环开环反应。
  • Synthesis of 1,6-dihydropyrimidines via copper-catalyzed multistep cascade reactions between O-propargylic aldoximes and isocyanates

    日期:2014.2
    Multi-step cascade reactions of O-propargylic oximes with isocyanates were carried out in the presence of copper catalysts to afford the corresponding 1,6-dihydropyrimidines in good yields. The multi-step reactions consisted of a 2,3-rearrangement, a [3+2] cycloaddition, decarboxylative ring opening involving a 1,4-hydrogen shift, and a 6π-electrocyclization.

  • Copper-Catalyzed Skeletal Rearrangement of O-Propargylic Aryloximes into Four-Membered Cyclic Nitrones - Chirality Transfer and Mechanistic Insight

    日期:2012.5
    Copper-catalyzed skeletal rearrangement of O-propargylic aryloximes (E)-1 were carried out to afford the corresponding four-membered cyclic nitrones 2 in good to excellent yields. The optimal reactions conditions of the highly regioselective reactions involved the use of [CuCl(cod)](2) in acetonitrile at 70 degrees C. In the case of (Z)-1, however, the reaction proceeded in the absence of the copper catalysts to afford the identical compound 2 in good yields. Furthermore, the reactions were also carried out using chiral substrates (R)-1 in the presence of Cu catalysts to afford (R)-2 with good levels of chirality transfer.

    (E)-O-Propargylic arylaldoximes were regioselectively converted, In the presence of copper catalysts, into their corresponding four-membered cyclic nitrones In good to excellent yields. The reactions proceeded via a tandem [2,3]-rearrangement and 4 pi-electrocyclization of the N-allenylnitrone intermediate and involved cleavage of the carbon-oxygen bond.
