  • A Silicon Tether Approach for Addition of Functionalized Radicals to Chiral α-Hydroxyhydrazones:  Diastereoselective Additions of Hydroxymethyl and Vinyl Synthons
    作者:Gregory K. Friestad、Sara E. Massari
    DOI:10.1021/jo035405r
    日期:2004.2.1
    Stereocontrolled additions of hydroxymethyl and vinyl groups to chiral α-hydroxyhydrazones can be achieved by radical cyclizations using bromomethyl or vinyl radical precursors tethered via a temporary silicon connection. Tin-mediated 5-exo radical cyclization of α-hydroxyhydrazones using a silicon-tethered bromomethyl group, followed by oxidative removal of the tether, provides anti-2-hydrazino 1
    羟基甲基和乙烯基向手性α-羟基hydr的立体控制加成可以通过使用经由临时硅连接拴系的溴甲基或乙烯基自由基前体的自由基环化来实现。使用硅连接的溴甲基基团,锡介导的α-羟基hydr的5-exo自由基环化,然后氧化脱除该链,可提供高收率的抗-2-肼基1,3-二醇。串联硅烷基乙烯基的α-羟基hydr的串联噻吩基自由基加成环化,然后用氟化钾处理,得到无环烯丙基抗-肼醇的收率很高。巯基加成环化方法已成功扩展到使用α,β-二羟基hydr,而无需事先保护或不进行羟基区分。两种反应类型的非对映选择均随附加基团A值的增加而增加,这与Beckwith-Houk模型对5-己烯基自由基环化中立体控制的预测相符。
  • Practical preparation of N-(1-alkynyl)sulfonamides and their synthetic utility in titanium alkoxide-mediated coupling reactions
    作者:Shuji Hirano、Yasuhiro Fukudome、Ryoichi Tanaka、Fumie Sato、Hirokazu Urabe

    日期:2006.4
    olefinic stereo-, and diastereoselective addition to aldehydes to give virtually single allyl alcohols. Alternatively, inter- or intramolecular coupling reaction between N-(1-alkynyl)sulfonamides and another acetylene or olefin with the above titanium alkoxide reagent generated the corresponding titanacycles, hydrolysis of which furnished stereo-defined (sulfonylamino)dienes or cyclic compounds.
    在CuI的催化存在下,将脂肪族和芳香族磺酰胺用1-溴-1-炔烃炔化,从而以良好或优异的收率得到N-(1-炔基)磺酰胺。在该炔基化过程中未观察到旋光磺酰胺的外消旋作用。从所得产生的乙炔钛络合物ñ - (1-炔基)磺酰胺和Ti(O-我-Pr)4 /2我-PrMgCl后行区域选择性,立体-烯烃,和非对映选择性加成到醛,得到几乎单一烯丙基酒精。或者,N之间的分子间或分子内偶联反应-(1-炔基)磺酰胺和另一种乙炔或烯烃与上述烷氧基钛试剂产生相应的钛环,其水解得到立体确定的(磺酰基氨基)二烯或环状化合物。
  • A kinetically controlled direct aldol addition of α-chloro thioesters via soft enolization
    作者:Rachel J. Alfie、Ngoc Truong、Julianne M. Yost、Don M. Coltart
    DOI:10.1016/j.tetlet.2016.11.010
    日期:2017.1
    direct aldol addition to aldehydes in the presence of MgBr2·OEt2 and i-Pr2NEt. At −78 °C the reaction proceeds in a kinetically controlled manner giving good diastereoselectivity. Significantly, the transformation is applicable to both enolizable and nonenolizable aldehydes. Moreover, excellent stereoselectivity results when a chiral nonracemic α-hydroxy aldehyde derivative is used. To our knowledge, this
    本文中我们报道了简单的α-氯代硫代酯在MgBr 2 ·OEt 2和i -Pr 2 NEt的存在下经历了软烯醇化反应,并直接向醛类中直接添加了羟醛。在-78°C,反应以动力学控制的方式进行,从而提供了良好的非对映选择性。明显地,该转化适用于可烯化和不可烯化的醛。此外,当使用手性非外消旋α-羟基醛衍生物时,可获得优异的立体选择性。据我们所知,这是基于动力学控制的基于软烯醇化的羟醛添加的首次报道。
  • Stereoselective Allylic Alkylations of Amino Ketones and Their Application in the Synthesis of Highly Functionalized Piperidines
    作者:Cynthia Prudel、Kai Huwig、Uli Kazmaier
    DOI:10.1002/chem.202000051
    日期:2020.3.9
    Chelated ketone enolates are excellent nucleophiles for allylic alkylations. Electron-withdrawing groups on the allyl moiety allow subsequent intramolecular Michael additions giving rise to piperidines with up to five stereogenic centers.
    螯合的酮烯酸酯是烯丙基烷基化的优良亲核试剂。烯丙基部分上的吸电子基团允许随后的分子内迈克尔加成产生具有多达五个立体异构中心的哌啶。
  • Ether-directed diastereoselectivity in catalysed Overman rearrangement: comparative studies of metal catalysts
    作者:Ieva Jaunzeme、Aigars Jirgensons
    DOI:10.1016/j.tet.2008.03.099
    日期:2008.6
    Ether-directed diastereoselectivity in Overman rearrangement of delta-methoxy and delta-TBDMSO substituted allylic trichloroacetimidates has been explored using PtCl2, PtCl4, AuCl and AuCl3 catalysts in comparison with commonly used Pd(II) catalysts. For both substrates the use of PtCl2 catalyst gave notably improved anti/syn-ratio of 1,2-aminoalcohol derivatives (anti/syn=11:1 for 5-methoxy; 6:1 for delta-TBDMSO) compared to all metal catalysts known to promote Overman rearrangement. Formation of 2-trichloromethyloxazoline was observed as a dominant side reaction in the metal catalysed rearrangement of a-methoxy substituted allylic trichloroacetimidates considerably reducing the yield of the desired product. This side reaction was suppressed when delta-TBDMS-ether was used as a directing group. (C) 2008 Elsevier Ltd. All rights reserved.
