    Formation of β-lactams fused to the pyranoid ring via the Mitsunobu reaction
    摘要:
    N-Tosyl-2-C-carbamoyl glycosides having the alpha-L-arabino- and beta-D-xylo- configuration form under Mitsunobu conditions 2-C:3-N-carbonyl-2,3-dideoxy-3-N-tosylamino-alpha-L-lyxo and beta-D-arabinopyranosides, respectively, having the beta-lactam ring fused to the pyranoid one; neither the formation of the gamma-lactam ring nor that of the 3,4-epoxide were observed. The gamma-lactam 2-C:4-N-carbonyl-2,4-dideoxy-4-N-tosylamino-beta-D-xylopyranoside can be obtained after protection of the 3-hydroxy group in the starting glycoside of alpha-L-arabino-configuration. The structure and configuration of methyl 2-C:3-N-carbonyl-2,3-dideoxy-3-N-tosylamino-beta-D-ribopyranoside and methyl 2-C:3-N-carbonyl-2,3-dideoxy-3-N-tosylamino-beta-D-erythro-pyranosid-4-ulose were proved by X-ray crystallography.

  • Synthesis of beta-L-2'-deoxy nucleosides
    申请人:Storer Richard
    公开号:US20050059632A1
    公开(公告)日:2005-03-17
    An improved process for the preparation of 2′-modified nucleosides and 2′-deoxy-nucleosides, such as, β-L-2′-deoxy-thymidine (LdT), is provided. In particular, the improved process is directed to the synthesis of a 2′-deoxynucleoside that may utilize different starting materials but that proceeds via a chloro-sugar intermediate or via a 2,2′-anhydro-1-furanosyl-nucleobase intermediate. Where an 2,2′-anhydro- 1 -furanosyl base intermediate is utilized, a reducing agent, such as Red-Al, and a sequestering agent, such as 15-crown-5 ether, that cause an intramolecular displacement reaction and formation of the desired nucleoside product in good yields are employed. An alternative process of the present invention utilizes a 2,2′-anhydro-1-furanosyl base intermediate without a sequestering agent to afford 2′-deoxynucleosides in good yields. The compounds made according to the present invention may be used as intermediates in the preparation of other nucleoside analogues, or may be used directly as antiviral and/or antineoplastic agents.
    提供了一种改进的2'-改性核苷和2'-脱氧核苷的制备工艺,例如,β-L-2'-脱氧胸苷(LdT)。特别是,改进的工艺针对的是2'-脱氧核苷的合成,该合成可能使用不同的起始材料,但都通过氯糖中间体或通过2,2'-脱水-1-呋喃糖核苷中间体进行。当使用2,2'-脱水-1-呋喃糖碱基中间体时,会采用还原剂(如Red-Al)和隔离剂(如15-冠-5醚),它们能引起分子内位移反应,并形成所需核苷产品的高收率。本发明的一种替代工艺使用2,2'-脱水-1-呋喃糖碱基中间体而不使用隔离剂,也能以高收率获得2'-脱氧核苷。根据本发明制成的化合物可以作为制备其他核苷类似物的中间体,或者可以直接用作抗病毒和/或抗肿瘤剂。
  • C–H···Anion Interactions Assisted Addition of Water to Glycals by Sterically Hindered 2,4,6-Tri-<i>tert</i>-butylpyridinium Hydrochloride
    作者:Ananya Mukherji、Pavan K. Kancharla
    DOI:10.1021/acs.orglett.0c00348
    日期:2020.3.20
    conjugate acid of the bulky base 2,4,6-tri-tert-butylpyridine, under mild conditions, catalyzes the synthesis of silyl-protected 2-deoxy-hemiacetals and their dimerized products from glycals at varying concentrations of water. The criticality of the concentration of water in the reaction outcome is indicative of a unique mechanistic pathway for the bulky pyridine salt and not via the general Brønsted acid

    Three compounds related to the AB fragments of ciguatoxin and gambiertoxin 4b and two diastereomers (at the C-2 position) of the ABC fragment of ciguatoxin have been synthesized in enantiomeric form. The stereochemistry of the C-2 position was introduced selectively from the corresponding pentose derivative.

    stabilities can be affected by hydrogen bonding from a substituent hydroxyl group to a ring oxygen. Additional evidence is provided in the case of the tetrahydropyran diols by [M]D values. The rate of reaction of the vicinal diols of these cyclic systems with glycol splitting reagents, and their zone electrophoretic mobility in an alkaline borate buffer is influenced by the presence of a ring oxygen.
