  • Synthetic Method for 2,2'-Disubstituted Fluorinated Binaphthyl Derivatives and Application as Chiral Source in Design of Chiral Mono-Phosphoric Acid Catalyst
    作者:Norie Momiyama、Hiroshi Okamoto、Masahiro Shimizu、Masahiro Terada
    DOI:10.1002/chir.22429
    日期:2015.8
    A practical synthetic method for 2,2'‐disubstituted fluorinated binaphthyl derivatives was achieved using magnesium bis(2,2,6,6‐tetramethylpiperamide) [Mg(TMP)2], prepared from LiTMP (2 equiv) and MgBr2 (1 equiv), which allows for access to a variety of fluorinated binaphthyl compounds. The utility of the fluorinated binaphthyl backbone was evaluated in F10BINOL derived chiral mono‐phosphoric acid
    使用达到2,2'-二取代的联化衍生物的实用合成方法双(2,2,6,6- tetramethylpiperamide)的Mg(TMP)2 ],从LiTMP(2当量)和MgBr制备2(1当量),可以接触到各种化联化合物。在F 10 BINOL衍生的手性单膦酸(R)-19中作为手性布朗斯台德酸催化剂评估了化联主链的效用。催化剂(R)-19在催化对映选择性亚基烯反应中表现出色,证明了化联骨架的潜力。手性27:464–475,2015年。 ©2015 Wiley Periodicals,Inc.
  • Magnesiation of<i>N</i>-Methyl-1, 3-propylenediaminoboryl Ferrocene

    N-methyl-1, 3-propylenediaminoboryl ferrocene (1-H) was obtained by a three-step synthesis: i) At first ferrocene was reacted with BBr3 to give dibromoboryl ferrocene (FcBBr2). ii) In a second step FcBBr2 was transformed into FcB(OMe)2 by treatment of FcBBr2 with Me3SiOMe. iii) Finally reaction of FcB(OMe)2 with H2NCH2CH2CH2NMeH yielded the boryl ferrocene 1-H. In addition we examined the metalation
    N-甲基-1, 3-丙烯二茂铁 (1-H) 通过三步合成获得: i) 首先二茂铁与 BBr3 反应得到二二茂铁 (FcBBr2)。ii) 在第二步中,通过用 Me3SiOMe 处理 FcBBr2,将 FcBBr2 转化为 FcB(OMe)2。iii) FcB(OMe)2 与 H2NCH2CH2CH2NMeH 最后反应得到二茂铁 1-H。此外,我们研究了 1-H 与 2, 2, 6, 6-四甲基哌啶 (TMP) 和 Li(TMP)/Mg(TMP)2 混合物的属化。1-H 与 0.5 当量 Mg(TMP)2 的反应定量产生均配复合物 Mg[1]2,而 1-H 与 1.5 和 2 当量 Mg(TMP)2 的属化得到产物混合物。然而,N,N'-二甲基-1,3-丙烯二茂铁 (1-Me) 和邻位甲基化衍生物 2-Me 和 3-Me(3-Me 在 1'-位置另外带有一个
  • Regioselective magnesiations of functionalized arenes and heteroarenes using TMP<sub>2</sub>Mg in hydrocarbons
    作者:Andreas Hess、Nurtalya Alandini、Hasret C. Guelen、Jan P. Prohaska、Paul Knochel
    DOI:10.1039/d2cc03856k
    日期:——
    hydrocarbon-soluble magnesium amide TMP2Mg (TMP = 2,2,6,6-tetramethylpiperidyl). This base showed excellent properties for the regioselective magnesiation of various arenes and heteroarenes bearing ethyl esters and carbamates under very mild reaction conditions. Subsequent trapping with aryl iodides (Negishi cross-coupling) gave access to a range of highly functionalized valuable building blocks.
    我们报告了一种新的烃溶性 TMP 2 Mg (TMP = 2,2,6,6-四甲基哌啶基) 的制备。该碱在非常温和的反应条件下显示出优异的区域选择性放大各种芳烃和带有乙基酯和氨基甲酸酯的杂芳烃的性能。随后用芳基化物进行捕获(Negishi 交叉偶联)可以获得一系列高度功能化的有价值的构建块。
  • Synthesis of an alkylmagnesium amide and interception of a ring-opened isomer of the important utility amide 2,2,6,6-tetramethylpiperidide (TMP)
    作者:Alan R. Kennedy、Jan Klett、Graeme McGrath、Robert E. Mulvey、Gemma M. Robertson、Stuart D. Robertson、Charles T. O’Hara
    DOI:10.1016/j.ica.2013.11.015
    日期:2014.2
    Two new magnesium complexes containing the important utility amide 2,2,6,6-tetramethylpiperidide (TMP) have been synthesised. Treating the magnesium bis(alkyl) reagent (Me3SiCH2)(2)Mg with a molar equivalent of TMP(H) in hydrocarbon medium produces the dimeric alkylmagnesium amide complex [(Me3SiCH2) Mg(mu-TMP)](2) 2, which was isolated in high yield. X-ray crystallography revealed that 2 was an unsymmetrical dimer as unusually the two TMP ligands adopt different conformations - one a chair, the other a twisted boat. Solution studies (multinuclear NMR and DOSY NMR spectroscopies) show that 2 undergoes a monomerisation and Schlenk equilibrium in d(8)-THF. When (Me3SiCH2)(2)Mg was reacted with two molar equivalents of TMP(H) in hydrocarbon medium [in an effort to prepare Mg(TMP)(2)] a crystalline sample of a surprising product, a tetranuclear triheteroanionic amide-alkoxide- amidoalkene [(TMP)Mg(mu-TMP)mu-N(H)C(Me)(2)CH2CH2CH2C(Me) = CH2}Mg(mu-OCH2SiMe3)](2) 3 was obtained. Complex 3 contains two unexpected anions, namely the alkoxide produced via oxygen insertion into a Mg-C bond, and the primary amidoalkene which is produced via ring opening of the TMP anion.

  • Protodeboronation of ortho- and para-Phenol Boronic Acids and Application to ortho and meta Functionalization of Phenols Using Boronic Acids as Blocking and Directing Groups
    作者:Chun-Young Lee、Su-Jin Ahn、Cheol-Hong Cheon
    DOI:10.1021/jo402174v
    日期:2013.12.6
    The first metal-free thermal protodeboronation of ortho- and para-phenol boronic acids in DMSO was developed. The protodeboronation was successfully applied to the synthesis of ortho- and meta-functionalized phenols using the boronic acid moiety as a blocking group and a directing group, respectively. Mechanistic studies suggested that this protodeboronation proceeds through the coordination of water to the boron atom followed by sigma-bond metathesis.
