    The present invention is directed to sulfated oligosaccharides having 4, 5 or 6 saccharidic units and wherein a glycosidic bond between two saccharide units is substituted by a C-C bond, and wherein the sulfation degree expressed as percentage of OH groups substituted by a OSO3- group is comprised between 50 and 100 %. The sulfated oligosaccharides according to the invention are useful as a drug, in particular in the treatment of angiogenesis, metastasis, and inflammation.

    maltohexaose mimics 12 (6,6‐dimer) and 13 (5′,5′‐dimer) in 30 % overall yield, respectively. Compounds 7 and 12 came from the dimerisation of CH2., primary radicals at C‐6, which could also abstract H‐5′, becoming CH3 and generating the C‐5′ quaternary radicals that dimerised in 8 and 13, respectively. These products were accompanied by the maltose derivatives 9, 10 and 11 a/b in 42 % overall yield and by the

  • Selectively Deoxygenated Derivatives of β-Maltosyl-(1→4)-Trehalose as Biological Probes
    作者:Hans Peter Wessel、Michel Trumtel、Rudolf Minder
    DOI:10.1080/07328309608005672
    日期:1996.7
    The four derivatives of beta-maltosyl-(1 --> 4)-trehalose have been synthesized, which are monodeoxygenated at the site of one of the primary hydroxyl groups. The tetrasaccharides were constructed in [2+2] block syntheses. Thus, 6'''-deoxy-beta-maltosyl-(1 --> 4)-trehalose was prepared by selective iodination of allyl 2,3,6,2',3'-penta-O-acetyl-beta-maltoside (3) followed by catalytic hydrogenolysis and coupling with 2,3-di-O-benzyl-4,6-O-benzylidene-alpha-D-glucopyranosyl 2',3',6'-tri-O-benzyl-alpha-D-glucopyranoside (9), and 6 ''-deoxy-beta-maltosyl-(1 --> 4)-trehalose by selective iodination of allyl 4',6'-O-isopropylidene-beta-maltoside (14), coupling with 9, and one-step hydrogenolysis at the tetrasaccharide level. For the synthesis of 6'-deoxy-beta-maltosyl-(1 --> 4)-trehalose, the diol 2,3-di-O-benzyl-4,6-O-benzylidene-alpha-D-glucopyranosyl 2',3'-di-O-benzyl-alpha-D-glucopyranoside (22) was selectively iodinated and glycosylated with acetobromomaltose followed by catalytic hydrogenolysis. The 6-deoxy-beta-maltosyl-(1 --> 4)-trehalose was obtained upon selective iodination of a tetrasaccharide diol.
