    通过串联还原-双还原胺化反应将N-苯基取代的吡咯烷,哌啶和氮杂双环
    摘要:
    通过分别在4-和5-氧醛的存在下催化还原硝基苯来合成N-苯基取代的吡咯烷和哌啶。该方法包括还原芳族硝基以得到N-苯基羟胺或苯胺,然后用两个羰基官能团进行还原胺化。单环体系通常以高收率形成并且易于纯化。该方法还扩展到由2-(3-氧代-丙基)环烷酮合成稠合的N-苯基氮杂双环。在具有相对于环烷酮羰基的酯基为α的底物中,观察到对转熔产物的高度非对映选择性。缺少该酯基的双环前体可得到顺式和反式产品。最后,与以前的报道相反,我们证明了在这些反应中苯胺可以代替硝基苯。

    Iron-Catalyzed Synthesis of α-Dienyl Five- and Six-Membered N-Heterocycles
    摘要:
    The iron‐catalyzed synthesis of α‐dienyl N‐heterocycles is reported. The method is cost‐effective, atom‐economic, and led to a range of substituted α‐dienyl heterocycles in moderate to good yields and diastereoselectivities. The α‐dienyl piperidines are key synthetic intermediates as demonstrated by the preparation of a panel of α‐polyenyl N‐heterocycles.

  • Neighboring group participation in Lewis acid-promoted [3 + 4] and [3 + 5] annulations. The synthesis of oxabicyclo[3.n.1]alkan-3-ones
    作者:Gary A. Molander、Kimberly O. Cameron
    DOI:10.1021/ja00056a002
    日期:1993.2
    2-(alkoxycarbon)-m-oxabicyclo[3.n.1]alkan-3-ones can be constructed by this process in which two new carbon-carbon bonds are generated. Unusually high regioncontrol is observed, and good to excellent stereochemical control can be achieved at virtually every position on the new carbocycles. Intramolecular neighboring group participation is proposed to explain the unusually high selectivities attained in the annulation

  • SULFONAMIDE-BASED ORGANOCATALYSTS AND METHOD FOR THEIR USE
    申请人:Carter Rich Garrett
    公开号:US20100184986A1
    公开(公告)日:2010-07-22
    Organocatalysts, particularly proline sulfonamide organocatalysts, having a first general formula as follows are disclosed. Embodiments of a method for using these organocatalysts also are disclosed. The method comprises providing a disclosed organocatalyst, and performing a reaction, often an enantioselective or diastereoselective reaction, using the organocatalyst. Solely by way of example, disclosed catalysts can be used to perform aldol reactions, conjugate additions, Michael additions, Robinson annulations, Mannich reactions, α-aminooxylations, α-hydroxyaminations, α-aminations and alkylation reactions. Certain of such reactions are intramolecular cyclizations used to form cyclic compounds, such as 5- or 6-membered rings, having one or more chiral centers. Disclosed organocatalysts generally are much more soluble in typical solvents used for organic synthesis than are known compounds. Moreover, the reaction yield is generally quite good with disclosed compounds, as is their enantioselective and diastereoselective effectiveness.

    作者:Masayuki Iwasaki、Sayuri Hayashi、Koji Hirano、Hideki Yorimitsu、Koichiro Oshima
    DOI:10.1021/ja067372d
    日期:2007.4.1
    fashion via a conformationally regulated six-membered cyclic transition state, the allylation reactions are highly regio- and stereospecific when homoallyl alcohols having a substituted allyl group are used. Whereas triarylphosphine is known to serve as a ligand for the palladium-catalyzed allyl transfer reactions, tricyclohexylphosphine proves to significantly expand the scopes of aryl halides to electron-rich
    在碳酸铯和钯催化剂存在下用芳基卤处理叔高烯丙醇时发生芳基卤的烯丙基化。烯丙基化反应将由以下步骤组成:(1)芳基卤化物与钯的氧化加成,(2)卤化物和高烯丙醇之间的配体交换,提供芳基(高烯丙氧基)钯,(3)钯醇盐的逆烯丙基化生成σ-烯丙基(芳基)钯,同时释放相关酮,和 (4) 生产性还原消除。由于逆烯丙基化步骤通过构象调节的六元环状过渡态以协同方式进行,因此当使用具有取代烯丙基的高烯丙醇时,烯丙基化反应具有高度的区域和立体定向性。虽然已知三芳基膦可作为钯催化的烯丙基转移反应的配体,但三环己基膦证明可以将芳基卤化物的范围显着扩展到富电子的芳基氯化物,将高烯丙醇的范围扩大到环状高烯丙醇。环状高烯丙醇的新芳基化开环反应允许以区域和立体特异性方式合成在远端具有支化或线性烯丙基芳烃部分的酮。

    作者:Long Guo Quan、Jin Kun Cha
    DOI:10.1016/s0040-4039(01)01868-8
    日期:2001.12
    The titanium-mediated cyclization of δ,ε-enones by using dichlorotitanium diphenoxide–cyclohexylmagnesium chloride diastereoselectively afforded cis-substituted cyclopentanols and was thus found to parallel the stoichiometric and catalytic titanocene-mediated reactions.
