Studies on the diastereoselective oxidation of 1-thio-β-D-glucopyranosides: synthesis of the usually less favoured RS sulfoxide as a single diastereoisomer
(Royal Society of Chemistry, 2015)
A detailed study on the diastereoselective oxidation of 1-thio-β-D-glucopyranosides is reported. It has been shown that the sense and the degree of stereochemical outcome of the oxidation are highly depen- dent on the ...

Improved non-covalent biofunctionalization of multi-walled carbon nanotubes using carbohydrate amphiphiles with a butterfly-like polyaromatic tail
(Springer, 2010)
We have developed an efficient strategy for the non-covalent functionalization of multi-walled carbon nanotubes (MWCNTs) which allows a biomimetic presentation of carbohydrates on their surface by π-π stacking interactions. ...

DMAP-Catalysed Sulfinylation of Diacetone-D-Glucose: Improved Method for the Synthesis of Enantiopure tert-Butyl Sulfoxides and tert-Butanesulfinamide
(Wiley Online Library, 2014-11)
An improved method for the tert-butanesulfinylation of diacetone glucose with tert-butanesulfinyl chloride is reported. The method is based on a beneficial effect of catalytic DMAP, which enhances both the rate of the ...

Pseudo enantiomeric mixed s/p ligands derived from carbohydrates for the 1,4-addition of phenyl boronic acid to cyclohexenone
(Royal Society of Chemistry, 2016)
The application of phosphinite-thioglycosides and phosphine-thioglycosides ligands in the Rh(I)-catalyzed 1,4-addition of phenylboronic acid to cyclohexenone is reported. Among the ligands tested, phosphinite-thioglycoside ...

Steric Tuning of Sulfinamide/Sulfoxides as Chiral Ligands with C1, Pseudo-meso, and Pseudo‑C2 Symmetries: Application in Rhodium(I)-Mediated Arylation
(ACS, 2019-07-31)
A new family of sulfinamide/sulfoxide derivatives was synthesized as chiral bidentate ligands by stereoselective additions of methylsulfinyl carbanions to N-tert-butylsulfinylimines. The new ligands, with C1, pseudo-meso, ...

Chiral sulfur derivatives in the allylation of acyl hydrazones: C 2-symmetric bis-sulfinamides as enhanced chiral organic promoters
(Royal Society of Chemistry, 2010-10)
Monosulfinamides and C2-symmetric bis-sulfinamides are convenient neutral chiral promoters in the allylation of acyl hydrazones, the nature of the spacer and the substituent at the sulfinyl sulfur are key elements for the ...

Sulfinamide Phosphinates as Chiral Catalysts for the Enantioselective Organocatalytic Reduction of Imines
(American Chemical Society, 2016-07)
A new type of chiral sulfinamide phosphinate catalysts with up to three stereogenic centers, readily accessible from commercially available starting materials, is reported. The naphthyl derivative SulPhos proved to be ...

Synthesis of 1D-glyconanomaterials by a hybrid noncovalent–covalent functionalization of single wall carbon nanotubes: a study of their selective interactions with lectins and with live cells
(Royal Society of Chemistry, 2015)
To take full advantage of the remarkable applications of carbon nanotubes in different fields, there is a need to develop effective methods to improve their water dispersion and biocompatibility while maintain- ing their ...

Design, synthesis and biological studies of a library of NK1-Receptor Ligands Based on a 5-arylthiosubstituted 2-amino-4,6-diaryl-3-cyano-4H-pyran core: Switch from antagonist to agonist effect by chemical modification
(Elsevier, 2017)
A library of 5-arylthiosubstituted 2-amino-4,6-diaryl-3-cyano-4H-pyrans has been synthesized as a new family of non-peptide NK1 receptor ligands by a one-pot cascade process. Their biological effects via interaction with ...
