    A concise total synthesis of (+)-deoxocassine and (−)-deoxoprosophylline from d-xylose
    摘要:
    A concise total synthesis of (+)-deoxocassine (1) and (-)-deoxoprosophylline (2) has been achieved for the first time from D-xylose. The key steps involved in these synthesis are alkyl Grignard reaction, S(N)2 substitution of mesylate by azide, Wittig reaction, and reductive amination. (C) 2012 Elsevier Ltd. All rights reserved.

  • A Route to “all-cis” 2-Methyl-6-Substituted Piperidin-3-ol Alkaloids from syn-(2R,1′S)-2-(1-Dibenzylaminomethyl)epoxide: Rapid Total Synthesis of (+)-Deoxocassine
    作者:Pierre-Yves Géant、Jean Martínez、Xavier J. Salom-Roig

    日期:2012.1
    to the synthesis of two cis-2-methyl-6-substituted piperidin-3-ols is described. syn-(2R,1S)-2-(1-Dibenzylaminomethyl) epoxide (13) was used as common building block. The key step involved oxirane ring opening of 13 by the nucleophilic lithium aza-enolate of hydrazones 12a and 12b. Subsequent hydrazone hydrolysis and intramolecular reductive amination afforded the alkaloid (+)-deoxocassine and a new

    日期:——
    A divergent, new, and highly stereoselective synthesis of cis-2,6-disubstituted piperidine natural products including isosolenopsins, deoxocassine, and spectaline was achieved from chiral aziridine decorated with appropriate alkyl chains for isosolenopsins or alkynyl groups for deoxocassine and spectaline at C2. The characteristic feature of this synthesis is one-pot sequential reactions under atmospheric

    Homochiral α-dibenzylamino aldehydes react with 4-butenylmagnesium bromide in diethyl ether at 0 °C to yield anti-β-amino alcohols in excellent yield and dr. These anti diastereoisomers were transformed into enantioenriched 2- and 2,6-substituted 3-piperidinols in good yields. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

  • Application of the Aza-Achmatowicz Oxidative Rearrangement for the Stereoselective Synthesis of the <i>Cassia</i> and <i>Prosopis</i> Alkaloid Family
    作者:Carolyn A. Leverett、Michael P. Cassidy、Albert Padwa
    DOI:10.1021/jo0616714
    日期:2006.10.1
    uted piperidin-3-ol alkaloids of the Cassia and Prosopis species are readily prepared by a combination of an aza-Achmatowicz oxidative rearrangement and dihydropyridone reduction followed by a stereoselective allylsilane addition to a N-sulfonyliminium ion. The stereochemical outcome of the reduction reaction can be attributed to steric hindrance between the pseudoaxially oriented 2,6-substituents
