  • Atropo-Enantioselective Total Synthesis of Knipholone and Related Antiplasmodial Phenylanthraquinones
    作者:Gerhard Bringmann、Dirk Menche、Jürgen Kraus、Jörg Mühlbacher、Karl Peters、Eva-Maria Peters、Reto Brun、Merhatibeb Bezabih、Berhanu M. Abegaz
    DOI:10.1021/jo020189s
    日期:2002.8.1
    The "lactone concept" has been efficiently employed for the first atropo-enantioselective synthesis of knipholone and related natural phenylanthraquinones. Besides the regio- and stereoselective construction of the biaryl axis, another important step was the "synthetically late" introduction of the C-acetyl group, either by a Friedel-Crafts type acetylation or by an ortho-selective Fries rearrangement
    “内酯概念”已被有效地用于苯丙醚酮和相关的天然苯基蒽醌的第一次熵-对映选择性合成。除了对联芳基轴的区域和立体选择性构建之外,另一个重要步骤是通过合成的乙酰弗里德-克拉夫茨型乙酰化反应或通过首先在简化模型上测试的邻位选择性弗里斯重排“合成后期”引入C-乙酰基系统并随后应用于天然产品及其简化类似物的高度阻转选择性制备以进行生物测试。这些天然联芳基,其前体和非天然类似物的合成可用性使得人们对这些有趣的联芳基的抗血浆活性进行了更广泛的研究。
  • The Atropo-Enantioselective Reduction of Configurationally Unstable Biaryl Hydroxy Aldehydes - A Novel Approach to Axially Chiral Biaryls
    作者:Gerhard Bringmann、Matthias Breuning
    DOI:10.1055/s-1998-1728
    日期:1998.6
    The oxazaborolidine-assisted atropo-enantioselective catecholborane reduction of configurationally unstable biaryl hydroxy aldehydes to axially chiral biaryl alcohols by (dynamic) kinetic resolution is achieved in enantiomeric ratios (er) of up to 92:8. Using the same chiral auxiliary, the M- or, optionally, the P-configurated atropisomer can be obtained in good er's - just by variation of the relative quantity of the achiral reductant. This hints at the existence of two competing reaction pathways with opposite asymmetric inductions. The enantiomeric ratios observed strongly depend on the relative steric demand of the substituents ortho to the biaryl axis.
    在噁唑硼烷辅助下,通过(动态)动力学解析将构型不稳定的双芳基羟基醛还原成轴向手性双芳基醇的邻苯二酚硼烷对映体选择性还原,对映体比(er)可达 92:8。使用相同的手性助剂,只需改变非手性还原剂的相对数量,就能以较好的对映体比(er's)获得 M-或 P-配置的异构体。这表明存在着两种具有相反不对称诱导作用的竞争反应途径。观察到的对映体比率在很大程度上取决于双芳基轴正向取代基的相对立体需求。
  • The ‘lactone method’: enantioselective preparation of novel P,N-biaryl ligands and their use in the synthesis of the biarylic alkaloids, ancistrotanzanine B and ancistroealaine A
    作者:Gerhard Bringmann、Robert-Michael Pfeifer、Petra Schreiber、Kristina Hartner、Michaela Schraut、Matthias Breuning
    DOI:10.1016/j.tet.2003.12.070
    日期:2004.5
    The ‘lactone method’ is a versatile tool for the atroposelective synthesis of axially chiral biaryls. The potential and scope of the concept are highlighted, in particular with respect to its use in the preparation of natural products and chiral auxiliaries. As a new application, the synthesis of novel axially chiral phosphineamines in enantiopure form is described; these ligands were used in the asymmetric
    “内酯法”是用于轴向手性联芳基的对映选择性合成的通用工具。强调了该概念的潜力和范围,特别是在其用于制备天然产物和手性助剂方面。作为一种新的应用,描述了对映体纯形式的新型轴向手性膦胺的合成。这些配体用于二元天然产物ancistrotanzanine B和ancistroealaine A的分子部分的不对称Suzuki交叉偶联。
  • The Atropo-Enantioselective Ring Opening of Achiral Lactone-Bridged Biaryls Using Chirally Modified Aluminum Hydrides
    作者:Gerhard Bringmann、Thomas Hartung
    DOI:10.1055/s-1992-26126
    日期:——
    The atropo-enantioselective preparation of the chiral biaryl 2-hydroxymethyl-1-(2-hydroxy-4, 6-dimethoxyphenyl)naphthalene (7) from 1,3-dimethoxy-6H-benzo [b]naphtho[1,2-d]pyran-6-one (3) is described, whereby two formal problems of stereoselective biaryl synthesis are independently solved: The carbon-carbon bond formation by the intramolecular aryl coupling of the ester-type prefixed aromatic halves, and the asymmetric induction at the pre-formed biaryl axis by the subsequent stereoselective ring-opening reaction, using chiral hydrogen nucleophiles.
    本研究描述了从 1,3 二甲基氧-6H-苯并 [b]萘并[1,2-d]吡喃-6-酮 (3) 手性 2-羟甲基-1-(2-羟基-4, 6-二甲氧基苯基)萘 (7) 的异丙烯-对映体选择性制备方法,从而独立解决了立体选择性双芳基合成的两个形式问题:利用手性氢亲核物,通过酯型预固定芳香半边的分子内芳基偶联形成碳-碳键,并通过随后的立体选择性开环反应在预形成的双芳基轴上进行不对称诱导。
  • Atropo-enantioselective reduction of configurationally unstable biaryl lactones with BINAL-H
    作者:Gerhard Bringmann、Matthias Breuning
    DOI:10.1016/s0957-4166(98)00503-5
    日期:1999.1
    The atropo-enantioselective reduction of configurationally unstable biaryl lactones with BINAL-H yields axially chiral biaryl alcohols in high enantiomeric ratios of up to 94:6 (er >99.5:0.5 after one crystallization step). Within this two-step reduction process the stereochemically deciding step is the first attack on the lactones and not the reduction of the likewise configurationally unstable biaryl lactol/hydroxy aldehyde intermediates, as evident from the non-stereoselective reduction of the latter under the same conditions.
