    The trisaccharide allyl O-(3,4-di-O-methyl-beta-D-glucopyranosyl)-(1----4)-O-(2,3-di-O-methyl-al pha-L- rhamnopyranosyl)-(1----2)-3-O-methyl-alpha-L-rhamnopyranoside was synthesized from partially methylated monosaccharide derivatives. Condensation of 1,4-di-O-acetyl-2,3-di-O-methyl-alpha-L-rhamnopyranose promoted by boron trifluoride etherate with the appropriate alcohol proceeded stereoselectively

This protecting group is stable under the Lewis acidic conditions of glycosylation, but it can be readily removed by the initial conversion into the corresponding 4-methoxyphenyl ether with use of a Pd catalyst, followed by oxidation with ammonium cerium (IV) nitrate [(NH 4 ) 2 Ce(NO 3 ) 6 ] (CAN).
    4-氯苯基醚被用作羟基官能团的新保护基团。通过使用二芳基三氟甲磺酸盐,可以很容易地将该基团引入糖羟基。通过使用催化剂三氟甲磺酸二芳基鎓,在邻位顺式二醇处区域选择性地引入该保护基团。该保护基团在糖基化的路易斯酸性条件下是稳定的,但可以通过使用 Pd 催化剂初始转化为相应的 4-甲氧基苯基醚,然后用硝酸铈 (IV) 化 [(NH 4 ) 2 Ce(NO 3 ) 6 ] (CAN)。
  • Synthesis of the Trisaccharide-Protein Conjugate of the Phenolic Glycolipid of Mycobacterium tuberculosis for the Serodiagnosis of Tuberculosis.

    The trisaccharide segment of the phenolic glycolipid (PGL) of Mycobacterium tuberculosis, 2-O-methyl-3-O-[3-O-(2, 3, 4-tri-O-methyl-α-L-fucopyranosyl)-α-L-rhamnopyranosyl]-α-L-rhamnopyranose, was synthesized in the form of the p-(2-methoxycarbonylethyl)phenyI glycoside by a stepwise condensation. 2, 4-Di-O-benzyl-3-O-acetyl-α-L-rhamnopyranosyl chloride was coupled to p-(2-methoxycarbonylethyl)phenyl 4-O-benzyl-2-O-methyl-α-L-rhamnopyranoside in the presence of silver triflate, and 2, 3, 4-tri-O-methyl-α-L-rhamnopyranosyl chloride was then coupled to the deacetylated disaccharide by the same procedure. The trisaccharide was deblocked and coupled to BSA, giving the neoglycoconjugate TB-NT-P-BSA. TB-NT-P-BSA showed its possibility as a useful tool for the serodiagnosis of tuberculosis.

    anosyl bromide or related disaccharides. Anomeric mixtures of the trisaccharide derivatives were separated by preparative t.l.c., deacetylated, and hydrogenolyzed, to give the pure trisaccharides. It had already been demonstrated that only those trisaccharides containing an intact, terminal 3,6-di-O-methyl-beta-D-glucopyranosyl unit are effective in inhibiting the specific binding between PGL-I and

    p-Nitrophenyl glycosides of 3-O-Me-beta-D-Glcp-(1 --> 3)-alpha-L-Rhap, alpha-L-Rhap-(1 --> 2)-6-deoxy-alpha-L-Talp, and 3-O-Me-beta-D-Glcp-(1 --> 3)-alpha-L-Rhap-(1 --> 2)-6-deoxy-alpha-L-Talp have been prepared, related to Mycobacterium avium. Various glycosylation methods have been used for the formation of the interglycosidic linkages. The p-nitrophenyl derivatives were converted into p-isothiocyanatophenyl glycosides, capable of forming neoglycoproteins. (C) 1997 Elsevier Science Ltd.
