    Expeditious preparation of triazole-linked glycolipids via microwave accelerated click chemistry and their electrochemical and biological assessments
    摘要:
    A series of triazole-linked ester-type glycolipids were efficiently prepared via a two-step sequence involving microwave accelerated 'click' chemistry and debenzylation. All carbon chain length varied O-alkynyl fatty esters used to couple with 1-azido-tetra-O-benzyl-beta-D-glucoside showed excellent tolerance to the microwave-assisted 1,3-dipolar cycloaddition (click reaction), forming the unique cycloadducts in almost quantitative yields of 92.9-99.0% within a quarter. The desired glycolipids were then readily afforded via the successive hydrogenolysis promoted by PdCl2/H-2. Their adsorption competence on gold electrode were evaluated through EIS (electrochemical impedance spectroscopy) measurement and the resulting structure-activity relationship (SAR) was discussed. In addition, the cytotoxicity of this triazolyl glycolipid class on HeLa (cervix cancer) cell line was identified by MTT assay. (C) 2010 Elsevier Ltd. All rights reserved.

    is applicable also to symmetrical dimers such as bithiophene and bifuran derivatives. Mechanistic studies suggest that the first step is addition reaction initiated by regioselective nucleophilic attack of the C3 of 2-aryl- and 2-heteroarylindoles to the internal carbon atom of the C[triple bond]C bond in propargyl ethers. The next stage is ring-closing S(N)2 process kicking out the alkoxy group and

    nucleophilic acyl substitution reactions. Herein, we report an unusual observation in which glycine propargyl ester derivatives displayed selective, base‐independent reactivity towards linear alkylamines under mild, metalfree conditions. Through global reaction route mapping (GRRM) modeling calculations, it is predicted that these observations may be governed by factors related to hydrogen‐bonding and intermolecular
