    对映选择性有机催化还原胺化
    摘要:
    第一个对映选择性有机催化还原胺化反应已经完成。新型手性磷酸催化剂的开发为受保护伯胺的对映选择性构建提供了一种方便的策略,并为杂环胺的还原胺化提供了一种高度立体选择性的方法。可以以高产率和出色的对映选择性容纳各种不同的酮和胺底物。这种新协议实现了还原胺化与亚胺还原的关键优势,因为从烷基-烷基酮衍生的酮亚胺对分离不稳定,使用这种直接有机催化还原胺化可以全面绕过这一基本限制。

  • Synthesis and Structural Aspects of<i>N</i>-Triflylphosphoramides and Their Calcium Salts-Highly Acidic and Effective Brønsted Acids
    作者:Magnus Rueping、Boris J. Nachtsheim、René M. Koenigs、Winai Ieawsuwan

    日期:2010.11.22
    emerged as a new class of potent Brønsted acid catalysts. In this paper we describe the efficient synthesis of various BINOL‐based N‐triflylphosphoramides and their calcium salts. Furthermore, X‐ray crystal structure analysis combined with energy‐dispersive X‐ray spectroscopy (EDX) measurements confirmed that the synthesised chiral N‐triflylphosphoramides are highly acidic metal‐free catalysts.

    A series of bulky monodentate phosphoramidite ligands were synthesized from chiral 3,3′-diaryl substituted BINOL derivatives and achiral or dendritic amines in good yields. Asymmetric hydrosilylation of styrenes with trichlorosilane in the presence of palladium complexes of these bulky ligands gave chiral silanes in high yields with excellent activity and productivity.

    intermediates with deconjugated butenolides and azlactones were accomplished by using a novel chiral hybrid P,S‐ligand and hydrogen bonding. By doing so, highly functionalized, optically active dihydroquinol‐2‐ones were produced with generally high reaction efficiencies and selectivities. Preliminary DFT calculations were performed to explain the high enantio‐ and diastereoselectivities.
    的偶极物质与亲核性的偶极亲和剂的催化不对称环加成反应,即反电子需求环加成反应,具有挑战性,并且开发不足。Pd催化的分子间烯丙基化的固有线性选择性和缺乏有效的手性配体可能是造成这一局限性的原因。在本文中,通过使用新型手性杂化P,S-配体和氢键,实现了此类中间体与去共轭的丁烯内酯和a内酯的两个环加成反应。通过这样做,可以生产出具有高官能度的旋光性二氢喹啉-2-酮,它们通常具有很高的反应效率和选择性。进行了初步的DFT计算,以解释高对映选择性和非对映选择性。
  • Synthesis and binding properties of chiral macrocyclic barbiturate receptors: application to nitrile oxide cyclizations
    作者:Brian S. Rasmussen、Unai Elezcano、Troels Skrydstrup
    DOI:10.1039/b110865b
    日期:2002.7.11
    A series of chiral macrocyclic receptors containing a barbiturate binding domain based on two 2,6-diaminopyridine groups has been synthesized with the purpose of exploiting these for asymmetric 1,3-dipolar cycloadditions. Each macrocyclic host was built possessing an (R)-BINOL or a modified deoxycholate moiety as the chiral unit connected to the barbiturate binding domain with varying lengths of spacer. All the hosts with the exception of one were found to effectively bind a barbiturate–cinnamic acid conjugate with association constants in the order of 104 M−1 in CDCl3. The 1,3-dipolar cycloaddition between several arylnitrile oxides and the cinnamate conjugates were examined in the presence of stoichiometric amounts of a chiral receptor affording two regioisomeric isoxazolines. Enantiomeric excesses of up to 30% were obtained in one case for the major regioisomer. In most cases, the enantiomeric excesses could be measured directly from the crude 1H-NMR spectra owing to the diastereomeric interaction between the isoxazoline cycloadduct and the chiral receptor. The relatively low enantiofacial selectivities at the CC double bond of the cinnamate were attributed to the non-planar orientation of the barbiturate–cinnamate conjugate with respect to the receptor, as previously noted for the binding of barbital to an achiral macrocyclic host (S.-K., Chang, E. Fan, D. Van Engen and A. D. Hamilton, J. Am. Chem. Soc., 1991, 113, 7640), directing the cinnamate unit away from the chiral unit.
    一系列基于两个2,6-二氨基吡啶基团的巴比妥酸盐结合域的手性大环受体已被合成,旨在利用它们进行不对称的1,3-偶极环加成反应。每个大环主体构建时含有一个(R)-BINOL或修饰的脱氧胆酸部分作为手性单元,通过不同长度的间隔基与巴比妥酸盐结合域相连。除一种外,所有受体均能有效结合巴比妥酸盐-肉桂酸共轭物,其在CDCl3中的结合常数为10^4 M^-1数量级。在手性受体的定量存在下,考察了几种芳基腈氧化物与肉桂酸共轭物之间的1,3-偶极环加成反应,生成两种区域异构的异恶唑啉。在某例中,主要区域异构体的对映体过量达到30%。在多数情况下,由于异恶唑啉环加合物与手性受体之间的非对映异构相互作用,对映体过量可以直接从粗1H-NMR谱图中测得。肉桂酸在CC双键处的相对较低的对映选择性归因于巴比妥酸盐-肉桂酸共轭物相对于受体的非平面取向,这一点与以前报道的巴比妥酸盐与非手性大环受体的结合情况相似(Chang等,1991),导致肉桂酸部分远离手性单元。
