  • A New Synthesis of Pteridines Substituted with Branched and Linear Alkenyl Groups at C(6). The Nitroso-Ene Reaction of 4-(Alkenoylamino)-5-nitrosopyrimidines
    作者:Fang-Li Zhang、W. Bernd Schweizer、Ming Xu、Andrea Vasella

    日期:2007.3
    Pteridines substituted with a 1,1-, 1,2-, or 1,1,3-substituted alkenyl group (mostly (E)-configured) at C(6) were synthesized in high yields by the intramolecular nitroso-ene reaction of 4-(alkenoylamino)-2-amino-6-benzyloxy-5-nitroso- and 4-(alkenoylamino)-2,6-diamino-5-nitrosopyrimidines. Thus, the N-alkenoyl nitrosopyrimidines 4 and 5 provided the pteridines 6 and 7, respectively, characterized

  • PRODUCTION OF CHIRALLY PURE AMINO ALCOHOL INTERMEDIATES, DERIVATIVES THEREOF, AND USES THEREOF

    A method of selectively preparing a chiral 2S-amino alcohol useful in preparation of an amide sulfonated or acylated with alkyl, substituted aryl or substituted heteroaryl is described. The method involves reacting a di-tert-butyl diazene-1,2-dicarboxylate with a (4S)-4-benzyl-3-[(S)-trifluoromethyl-alkyl substituted alkanoyl]-1,3-oxazolidin-2-one to afford a di-tert-butyl 1-(1S,2S)-([(4S)-4-benzyl-2-oxo-1,3-oxazolidine-3-yl]-carbonyl}-trifluoromethyl-alkyl substituted alkyl)hydrazine-1,2-dicarboxylate. This dicarboxylate is then reduced to yield di-tert-butyl 1-(1S,2S)-[trifluoromethyl-alkyl substituted alkyl]hydrazine-1-(hydroxymethyl)-1,2-dicarboxylate. The resulting product is deblocked with an acid to yield the acid addition salt of (2S,3S)-trifluoro-hydrazino-methyl alkan-1-ol. The acid addition salt of (2S,3S)-trifluoro-2-hydrazino-methyl alkan-1-ol is hydrogenated in the presence of a suitable metal catalyst to yield the amino alcohol (2S,3S)-2-amino-trifluoro-methyl alkan-1-ol HCl.

  • Studies of the New Reactivity of Chiral Acrylamides and Unprotected Pyrroles: Diastereoselective and Carbonyl Compatible 1,4-Addition
    作者:Samir Bouzbouz、Alexandre Gratais、Xavier Pannecoucke
    DOI:10.1055/s-0033-1341275
    日期:——
    A diversity of new functionalized cyclic and acyclic chiral pyrroloamides compounds were synthesized in good yields and diastereoselectivities in the case of cyclic pyrroloamides. This simple and robust process involves the creation of a C-C bond between unprotected pyrroles and cyclic or hindered chiral acrylamides.

  • Oxazoline−Oxazinone Oxidative Rearrangement. Divergent Syntheses of (2<i>S</i>,3<i>S</i>)-4,4,4-Trifluorovaline and (2<i>S</i>,4<i>S</i>)-5,5,5-Trifluoroleucine
    作者:Julie A. Pigza、Tim Quach、Tadeusz F. Molinski
    DOI:10.1021/jo900654y
    日期:2009.8.7
    Stereoselective syntheses of the valuable fluorinated amino acids (2S,3S)-4,4,4-trifluorovaline and (2S,4S)-5,5,5-trifluoroleucine have been achieved starting from 4,4,4-trifluoro-3-methylbutanoic acid by using a conceptually simple transformation: conversion to a chiral oxazoline, SeO2-promoted oxidative rearrangement to the dihydro-2H-oxazinone, and face-selective hydrogenation of the C=N bond, followed by hydrogenolysis-hydrolysis. The transformation is limited by the tendency of the intermediate beta-trifluoromethyldihydrooxazinone to undergo imine-enamine isomerization. Both amino acids were obtained as configurationally pure hydrochloride salts identical in all respects with those in literature reports,
