  • Regioselective Benzoylation of 6-O-Protected and 4,6-O-Diprotected Hexopyranosides as Promoted by Chiral and Achiral Ditertiary 1,2-Diamines
    作者:Guixian Hu、Andrea Vasella
    DOI:10.1002/hlca.200290018
    日期:2002.12
    Monobenzoylation of triols (6-O-silylated glycopyranosides) or diols (4,6-O-benzylidenated glycopyranosides) with benzoyl chloride and triethylamine at −60° to 23° is promoted by catalytic amounts of ditertiary 1,2-diamines. The regioselectivity depends mostly on the structure of the alcohols; it is modulated by the configuration and constitution of the diamines, as shown by comparing the effect of Oriyama's

    Protection of 2,3,4-O-unprotected α-galacto- and α-fucopyranosides with BzCN and DMAP/DIPEA as the base afforded directly and regioselectively the 3-O-unprotected derivatives. The rationale for these studies was to take advantage of the eventual cooperativity of the “cyanide effect” and “the alkoxy group mediated diol effect”. This way, even the totally unprotected α-galactopyranosides could be regioselectively
    用BzCN和DMAP / DIPEA作为碱保护2,3,4- O-未保护的α-半乳糖和α-呋喃果糖苷直接和区域选择性地提供了3- O-未保护的衍生物。这些研究的基本原理是利用“氰化物效应”和“烷氧基基团介导的二醇效应”的最终协同作用。这样,甚至完全未保护的α-吡喃半乳糖苷也可以区域选择性地转化为相应的2,4,6- O-保护的衍生物。这些构件的巨大效用已在有效的三糖合成中得到了证明。

  • Dispiroketals in synthesis (Part 17): Regioselective protection of D-glucopyranoside D-galactopyranoside and D-mannopyranoside substrates.
    作者:Paul J. Edwards、David A. Entwistle、Christophe Genicot、Steven V. Ley、Giuseppina Visentin

    Chiral recognition of enantiomeric trans-1,2-diol relationships leading to regioselective formation of 1,8,13,16-tetraoxadispiro[5.0.5.4] hexadecanes (dispiroketals) of various D-glucopyranoside, D-galactopyranoside and D-mannopyranoside substrates is described. Regioselectivity is achieved using the enantiomerically pure disubstituted tetrahydro-6,6'-bi-2H-pyrans 1, 2, 3, 4 and 5. Facile removal of the dispiroketal protecting group from a number of the sugar adducts has been achieved.
  • Synthesis of a trisaccharide repeat of the zwitterionic Sp1 capsular polysaccharide utilizing 2-azido-4-benzylamino-4N,3-O-carbonyl-2,4,6-trideoxy-d-galactopyranosyl trichloroacetimidate
    作者:Ithayavani Iynkkaran、David R. Bundle
    DOI:10.1016/j.carres.2013.05.005
    日期:2013.8
    2-Azido-4-benzylamino-4N,3-O-carbonyl-2,4,6-trideoxy-D-galactopyranosyl trichloroacetimidate 2 conveniently prepared in six steps from 6-deoxy-D-glucal glycosylated a selectively protected alpha 1,3 linked methyl galabioside to afford the trisaccharide skeleton of a repeating unit of the Sp1 zwitterionic capsular polysaccharide. Lithium hydroxide hydrolysis of the 3,4-cyclic carbamate permitted the creation of a 2-acetamido-4-amino-2,4,6-trideoxygalactose residue. Selective cleavage of p-methoxybenzyl ethers by trifluoroacetic acid gave a selectively deprotected trisaccharide with two hydroxymethyl groups that were oxidized by the TEMPO reagent to afford access to trisaccharide glycoside 1 containing 2-acetamido- 4-amino-2,4,6-trideoxygalactose and two galacturonic acid residues.
