  • Syntheses and reactions of saturated and 2,3-unsaturated vinyl and 1′-substituted-vinyl glycosides
    作者:Anna de Raadt、Robert J. Ferrier
    DOI:10.1016/0008-6215(92)84153-j
    日期:1992.9
    Abstract Reaction of tetra- O -α- d -glucopyranosyl bromide with bis(acylmethyl)mercurys [Hg (CH 2 COR) 2 ] afforded acetylated vinyl [by use of bis(formylmethyl)mercury] or 1′-substituted-vinyl β- d -glucopyranosides 11–13 in high yields. When used together with phenyl 4,6-di- O -acetyl-2,3-dideoxy-1-thio-α- d - erythro -hex-2-enopyranoside, these reagents gave analogous vinyl 4,6-di- O -acetyl-2
    摘要四-O-α-d-葡萄糖化物与双(酰基甲基)[Hg(CH 2 COR)2]反应,得到乙酰化的乙烯基[通过使用双(甲酰基甲基)]或1'-取代的乙烯基β- d-葡萄糖苷11-13高产。当与苯基4,6-二-O-乙酰基-2,3-二脱氧-1-代-α-d-赤-己基-2-烯喃糖苷一起使用时,这些试剂可得到类似的乙烯基4,6-二-O-乙酰-2,3-二脱氧-d-赤-己基-2-烯喃糖苷20-23,在用路易斯酸处理后,异构化为相应的C-糖基化合物,即(4,6-di-O-acetyl-2 ,3-dideoxy-d-赤型-hex-2-enopyranosy)乙醛(24,25)或相应的糖基化甲基酮26,27。制备C-3-支链糖的新途径涉及用双(苯甲酰基甲基)-处理上述代糖苷或不饱和乙烯基糖苷。

    日期:2001.6
    A variety of functionalized C-pseudoglycals (pseudoglycal C-glycosides or C-hex-2-enopyranosides) have been obtained in excellent yields and stereoselectivity from the Yb(OTf)3-catalyzed reaction of tri-O-acetyl glucal with silylated nucleophiles such as allyl and propargyl silanes and silyl enol ethers.

    作者:Rupa Bai Addanki、Suvendu Halder、Pavan K. Kancharla
    DOI:10.1021/acs.orglett.2c00062
    日期:2022.2.25
    We demonstrate here that the strained and bulky protonated 2,4,6-tri-tert-butylpyridine (TTBPy) triflate salt serves as a mild and efficient organocatalyst for the diastereoselective C-Ferrier glycosylation of various glycals. The importance of the role of the 1/2 H2O molecule trapped in the catalyst has been disclosed. The mechanism of action involves unique anionic triflate and H2O hydrogen-bond
    我们在此证明,紧张且庞大的质子化 2,4,6-三叔丁基吡啶 (TTBPy) 三氟甲磺酸盐可作为一种温和而有效的有机催化剂,用于各种糖基的非对映选择性C- Ferrier 糖基化。已经公开了捕获在催化剂中的1/2 H 2 O分子的作用的重要性。作用机制涉及独特的阴离子三氟甲磺酸酯和 H 2 O 氢键相互作用,有助于活化烯丙基硅烷,提供前所未有的非对映选择性苯基烯丙基 Ferrier 糖苷。
  • Molybdenum-Catalyzed Allylic Substitution in Glycals: A C-C Bond-Forming Ferrier-Type Reaction
    作者:Andrei V. Malkov、Benjamin P. Farn、Nigel Hussain、Pavel Kočovský
    DOI:10.1135/cccc20011735
    日期:——

    The mild, Lewis-acidic complexes [Mo(CO)4Br2]2, (MeCN)2Mo(CO)3(SnCl3)Cl, and (acac)2Mo(OTf)2 have been found to catalyze the C(1)-specific C-glycosylation reaction of glycal acetates 1-3 with silyl enol ethers 4a-4c and electron-rich aromatics 5a, 5b (PhOMe, PhOH). While silyl enol ethers produce predominantly α-C-glycopyranosides (with 2 : 1 to 4 : 1 selectivity), aromatics tend to afford mainly β-C-glycopyranosides (2 : 1 to 3 : 1) in a thermodynamically controlled process.

    轻度的、Lewis酸性的配合物[Mo(CO)4Br2]2,(MeCN)2Mo(CO)3(SnCl3)Cl和(acac)2Mo(OTf)2被发现能催化糖醇醋酸酯1-3烯醇醚4a-4c以及富电子芳香化合物5a5b(PhOMe,PhOH)之间的C(1)特异性糖基化反应。虽然烯醇醚主要生成α-C-糖基喃苷(2:1至4:1的选择性),但芳香化合物倾向于主要产生β-C-糖基喃苷(2:1至3:1)在一个热力学控制的过程中。

    to observe this ionic species, its extended lifetime in superacid solutions allowed its characterization by NMR‐based structural analysis supported by DFT calculations. This allyloxycarbenium ion was further exploited in the Ferrier rearrangement to afford unsaturated nitrogen‐containing C‐aryl glycosides and C‐alkyl glycosides under superacid and flow conditions, respectively.
    费里尔(Ferrier)于1962年报道,将糖类转化为2,3-不饱和糖基衍生物的过程涉及α,β不饱和糖基阳离子,这是一种尚难于观察的离子性离子。在本文中,虽然TfOH和流动条件的组合未能观察到该离子种类,但其在超强酸溶液中的延长寿命使其能够通过DFT计算支持的基于NMR的结构分析进行表征。该烯丙基氧碳鎓离子进一步在Ferrier重排中得到利用,分别在过酸和流动条件下提供了不饱和的含氮C-芳基糖苷和C-烷基糖苷。
