    Total Synthesis of Desoxoprosophylline:  Application of a Lactam-Derived Enol Triflate to Natural Product Synthesis
    摘要:
    The total synthesis of desoxoprosophylline 1 from a piperidinone-derived enol triflate 8 has been realized and is one of the first applications of such lactam-derived triflates to natural product synthesis. Palladium-catalyzed methoxycarbonylation of 8 followed by 1,2-reduction and protection introduces the required C2 hydroxymethyl group, affording 10. The C3 hydroxy function is stereoselectively added by a novel N-tosylenamide hydroboration (de 88%), and the final C6 dodecyl chain is incorporated with complete stereocontrol, in a single step, via an N-tosyliminium ion-allylsilane coupling. Deprotection gives the natural product in an efficient 7.5% yield over nine steps.

  • Synthesis of Enantioenriched 2- and 2,6-Substituted Piperidin-3-ols from α-Dibenzylamino Aldehydes
    作者:José M. Andrés、Rafael Pedrosa、Alfonso Pérez-Encabo
    DOI:10.1002/ejoc.200601009
    日期:2007.4
    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)

    Intramolecular N-alkylation of D-glucose-derived substrate 21E proceeded in an SN2′ mode smoothly in the presence of a Pd(O)catalyst and n-Bu4NI. The major cyclization product, a 2,6-dialkylated piperidine 22t, was effectively converted into the title alkaloids.

    Approaches toward the syntheses of alkaloids belonging to the 2,6-disubstituted 3-hydroxypiperidine and cis-decahydroquinoline (cis-DHQ) classes of alkaloids are developed, starting from a common chiral nonracemic bicyclic lactam lactone (BLL). Two key δ-lactam intermediates, (5S,6S)-5-hydroxy-6-hydroxymethyl- and (5S,6S)-5-hydroxy-6-methylpiperidin-2-ones, are prepared; the latter δ-lactam is obtained
