  • Catalytic Hydroetherification of Unactivated Alkenes Enabled by Proton‐Coupled Electron Transfer
    作者:Elaine Tsui、Anthony J. Metrano、Yuto Tsuchiya、Robert R. Knowles
    DOI:10.1002/anie.202003959
    日期:2020.7.13
    We report a catalytic, lightdriven method for the intramolecular hydroetherification of unactivated alkenols to furnish cyclic ether products. These reactions occur under visible‐light irradiation in the presence of an IrIII‐based photoredox catalyst, a Brønsted base catalyst, and a hydrogen‐atom transfer (HAT) co‐catalyst. Reactive alkoxy radicals are proposed as key intermediates, generated by direct
    我们报告了一种催化光驱动方法,用于未活化烯醇的分子内加氢醚化以提供环醚产品。这些反应在 Ir III基光氧化还原催化剂、布朗斯台德碱催化剂和氢原子转移 (HAT) 助催化剂存在下在可见光照射下发生。反应性烷氧基被认为是关键中间体,是通过质子耦合电子转移机制直接均裂激活醇 O−H 键而产生的。该方法表现出广泛的底物范围和高官能团耐受性,并且适应多种烯烃取代模式。还提出了证明该催化系统扩展到碳醚化反应的结果。
  • Directed Dihydroxylation of Cyclic Allylic Alcohols and Trichloroacetamides Using OsO<sub>4</sub>/TMEDA
    作者:Timothy J. Donohoe、Kevin Blades、Peter R. Moore、Michael J. Waring、Jon J. G. Winter、Madeleine Helliwell、Nicholas J. Newcombe、Geoffrey Stemp
    DOI:10.1021/jo026161y
    日期:2002.11.1
    The oxidation of a range of cyclic allylic alcohols and amides with OsO4/TMEDA is presented. Under these conditions, hydrogen bonding control leads to the (contrasteric) formation of the syn isomer in almost every example that was examined. Evidence for the bidentate binding of TMEDA to OsO4 is presented and a plausible mechanism described.
    介绍了用OsO4 / TMEDA氧化一系列环状烯丙醇和酰胺的方法。在这些条件下,几乎在每个所研究的实施例中,氢键控制导致顺式异构体的(对映体)形成。提供了TMEDA与OsO4的双齿结合的证据,并描述了一个可能的机制。
  • Synthesis of macrocyclic scaffolds suitable for diversity-oriented synthesis of macrolides
    作者:Michael E. Grimwood、Henrik C. Hansen
    DOI:10.1016/j.tet.2009.07.088
    日期:2009.9
    Synthesis of macrocyclic glycal-based scaffolds for diversity-oriented synthesis was studied and demonstrated using macrocyclic enyne ring-closing metathesis. The roles of ring size, alkyne substitution, and orientation relative to the glycal were studied. In all cases, the cyclization showed preference for the thermodynamically favored endo-mode of closure and a trans-double bond at the ring-closure

  • HIGHLY DEOXYGENATED SUGARS. I. C2-BRANCHED GLUCOSE DERIVATIVES AND CARBON LINKED DEOXYGENATED DISACCHARIDES<sup>*</sup>
    作者:Karsten Krohn、Ulrich Flörke、Dietmar Gehle
    DOI:10.1081/car-120014904
    日期:2002.1.10
    Triacetylglucal (1) is converted with high alpha-selectivity (>9:1) to the corresponding 2,3-unsaturated allyl and benzyl glycosides 2 and 3 using ferric chloride as the catalyst. The 6-O-silyl-protected allylic alcohol 5 is transformed to the 3,4-unsaturated C2-branched ester 6 or the amide 7 by Claisen rearrangement. The highly deoxygenated iodo lactone 8, resulting from the amide 6 by iodolactonization, is a versatile starting material for chiral building blocks 9-12. The 3,4-unsaturated C2-branched ester 6 is reduced to the aldehyde 14 and converted to a carbon linked disaccharide analogue 16 via cycloaddition with Danishefky's diene.

    and C-O π-bond functionality, as atom-less protecting groups as well as an anomeric directing group (via a Pd-π-allyl), highlights the atom-economical aspects of the route to a divergent set of natural and unnatural oligosaccharides (i.e., various d-/l-diastereomers of oligosaccharides as well as deoxysugars which lack C-2 anomeric directing groups). For example, in only 12 steps, the construction of
    由于需要多个步骤以及许多选择性保护和脱保护,寡糖合成受到阻碍。在此,我们报告了一种用于生物和药物结构活性研究的各种寡糖基序的高效从头途径。整体效率的关键是明智地使用不对称催化和合成设计。这些绿色原则包括双向使用高度立体选择性催化(Pd(0)催化的糖基化/后糖基化)。此外,CC 和 CO π 键官能团的化学选择性使用,作为无原子保护基团以及异头导向基团(通过 Pd-π-烯丙基),突出了通往发散路线的原子经济方面一组天然和非天然寡糖(即,低聚糖的各种 d-/l-非对映异构体以及缺乏 C-2 异头导向基团的脱氧糖)。例如,仅用 12 个步骤,就从非手性酰基呋喃构建了具有 35 个立体中心的高度支化七糖。
