  描述：

  2-benzoyloxyethyl 2-acetamido-3-O-benzoyl-2,4-dideoxy-β-L-threo-hex-4-ene-dialdo-1,5-pyranoside 在 四氮唑 、 叔丁基过氧化氢 、 四(三苯基膦)钯 、 5,5-二甲基-1,3-环己二酮 、 三乙胺 作用下， 以 四氢呋喃 、 二氯甲烷 为溶剂， 反应 46.5h， 生成 Phosphoric acid (5R,6R)-5-acetylamino-6-(2-hydroxy-ethoxy)-5,6-dihydro-pyran-(2E)-ylidenemethyl ester (2R,3S,4R,5R)-5-(4-amino-2-oxo-2H-pyrimidin-1-yl)-3,4-dihydroxy-tetrahydro-furan-2-ylmethyl ester

  Efficient Sialyltransferase Inhibitors Based on Glycosides of N-Acetylglucosamine

  摘要：

  D-Glucosamine was transformed into phenyl and 2-benzoyloxyethyl N-acetylglucosamine beta-glycosides 6a and 6b, respectively. Transformation of 6a,b into 6-O-unprotected N-acetylglucosamine derivatives 9a,b permitted the generation of an aldehyde group in the 6-position, Treatment of these intermediates with base afforded unsaturated aldehyde derivatives 10a,b, which are structural mimics of 2,3-dehydroneuraminic acid. H-Phosphonate addition to the aldehyde group and attachment of the cytidine monophosphate residue to the generated hydroxy group gave fully protected transition state analogues of cytidine monophosphate-N-acetylneuraminic acid 14a,b. Liberation of the unprotected compounds 1ah,l and 1lbh,l led to excellent inhibitors of alpha(2-6) -sialyltransferase from rat liver. Variation of the protective group cleavage procedure for 14a,b led to formal loss of phosphate, thus resulting in diene derivatives (E)-/(Z)-2a,b, which also exhibited inhibitory properties.
