  • Chemoenzymatic synthesis of ethyl 1-thio-(β-D-galactopyranosyl)-O-β-D-glycopyranosyl disaccharides using the β-galactosidase from Bacillus circulans

    日期:1996.3
    Different ethyl 1-thio-β-D-disaccharides have been synthesised by transgalactosylation using the β-galactosidase from Bacillus circulans as biocatalyst. This β-galactosidase shows mainly a β-1–4 specificity in the galactosyl transfer. Gal-β-(1–4)-O-β-D-GlcSEt 15 was obtained in 36% yield, Gal-β-(1ndash;4)-O-α-D-GlcSEt 19 in 30% yield, Gal-β-(1–4)-O-β-D-GalSEt 17 in 60% yield, Gal-β-(1–4)-O-β-D-GalNAcSEt

  • Synthesis and Properties ofO-Glycosyl Calix[4]Arenes (Calixsugars)
    作者:Alessandro Dondoni、Alberto Marra、Marie-Christine Scherrmann、Alessandro Casnati、Francesco Sansone、Rocco Ungaro
    DOI:10.1002/chem.19970031108
    日期:1997.11
    AbstractModelO‐glycosylation reactions at either rim of calix[4]arenes are described with the aim of providing access to a new family of carbohydrate‐containing calixarene derivatives named calixsugars. One or two sugar moieties (D‐mannofuranose and D‐glucopyranose) were introduced at the lower rim of the parent calix[4]arene by glycosylation of the phenolic hydroxyl groups by means of a Mitsunobu reaction. Tetrapropoxy calix[4]arenes bearing two or four hydroxymethyl groups at the upper rim were coupled with perbenzoylated thioethyl D‐galactoside and D‐lactoside in the presence of the thiophilic promoter copper(III) triflate. In this way β‐linked bis‐ and tetrakis‐O‐galactosyl calix[4]arenes were obtained in good yield, the latter showing some solubility in water. For theO‐lactosyl derivatives only the bis‐substituted compound could be obtained because of the competing formation of an intramolecular ether linkage between 1,3‐hydroxymethyl groups. Preliminary binding studies showed some affinity of the galactose‐containing calixsugars toward charged carbohydrates and dihydrogen phosphate anion.
