  • One-pot sequential cross-metathesis/hydride reduction: highly stereoselective synthesis of primary (E)-allylic alcohols from terminal olefins
    作者:Tapas Paul、Gopal Sirasani、Rodrigo B. Andrade

    日期:2008.5
    Several di- and trisubstituted primary (E)-allylic alcohols have been prepared from the corresponding terminal olefins in a highly stereoselective manner (>20:1 E/Z) by sequencing olefin cross-metathesis (CM) with hydride reduction (DIBAL-H) in good yields utilizing only commercially available reagents in a one-pot fashion. The method is a reliable alternative to the direct CM of terminal olefins with

    purity by reduction of the ynone precursor 4 with the Noyori N-tosyl-1,2-diphenylethylenediamineruthenium cymene catalyst is described. The mesylate derivative of the (S) enantiomer (1c) is converted in situ to an allenylzinc or indium reagent in the presence of a catalyst derived from Pd(OAc)2 and Ph3P and either Et2Zn or InI. A second in situ addition of these reagents to aldehydes leads to anti homopropargylic

  • A Cyclic Acetal Tethered Intramolecular Diels-Alder Cycloaddition. Studies Directed toward a Total Synthesis of (±)-Fusidilactone C
    作者:Richard P. Hsung、Jiashi Wang、Sunil K. Ghosh、Yonggang Wei、John B. Feltenberger
    DOI:10.3987/com-10-s(e)93
    日期:——
    Efforts toward a synthesis of (+/-)-fusidilactone C is described here featuring a novel cyclic acetal tethered intramolecular Diels-Alder strategy. This unique and facile IMDA turned out to be highly endo-selective [endo-I and endo-II], as assessed from our mechanistic analyses. When using protic solvents or Lewis acids, the endo-I selectivity was greatly enhanced. Thus, it proved to be a real challenge to circumvent this excellent stereochemical outcome, which is undesired for the total synthesis, as an exo-II selectivity is desired. Progress was made to use the endo-II cycloadduct and to access the desired trans-2-oxadecalin motif in (+/-)-fusidilactone C.
  • Sequencing cross-metathesis and non-metathesis reactions to rapidly access building blocks for synthesis
    作者:Gopal Sirasani、Tapas Paul、Rodrigo B. Andrade
    DOI:10.1016/j.tet.2011.01.080
    日期:2011.3
    The olefin cross-metathesis reaction has been sequenced with four common organic transformations in a one- or two-pot manner to rapidly access useful building blocks. Those reactions are: (1) phosphorus-based olefination (e.g.. Wittig and Horner-Wadsworth-Emmons); (2) hydride reduction; (3) Evans propionate aldol reaction; (4) Brown allyl- and Roush crotyl-boration. The products of these reactions include stereodefined 2,4-dienoates, trans allylic alcohols, syn-propionate aldols, and chiral non-racemic homoallylic alcohols, respectively. Many of these intermediates have been carried further to natural products, demonstrating the utility of the methodology. (C) 2011 Elsevier Ltd. All rights reserved.
  • De Novo Synthesis of 2-Substituted <i>syn</i>-1,3-Diols via an Iterative Asymmetric Hydration Strategy
    作者:Md. Moinuddin Ahmed、Matthew S. Mortensen、George A. O'Doherty
    DOI:10.1021/jo061200h
    日期:2006.9.1
    The enantioselective syntheses of several protected 4-substituted syn-3,5-dihydroxy carboxylic esters have been achieved from the corresponding achiral (E,E)- or (E,Z)-1,3-dienoates. The route relies upon an enantio- and regioselective Sharpless dihydroxylation and a palladium-catalyzed reduction to form gamma-substituted delta-hydroxy-1-enoates. The resulting delta-hydroxy-1-enoates are subsequently converted into benzylidene-protected 4-substituted syn-3,5-dihydroxy carboxylic esters in one step. The benzylidene-protected 3,5-dihydroxy carboxylic esters are produced in good overall yields (20-54%) and high enantiomeric excess (73- 97% ee).
