Selenium and Sulphur Derivatives of Hydroxytyrosol: Inhibition of Lipid Peroxidation in Liver Microsomes of Vitamin E-deficient Rats
(Springer Nature, 2019)
Purpose: The objective of this study was to evaluate the capacity of modified phenols synthesized from hydroxytyrosol, a natural olive oil phenol, specifically those containing a selenium or sulphur group, to inhibit lipid ...

Bifunctional Squaramide Organocatalysts for the Asymmetric Addition of Formaldehyde tert-Butylhydrazone to Simple Aldehydes
(Wiley-Blackwell, 2018)
The nucleophilic addition of formaldehyde tert-butylhydrazone to simple aldehydes (a formal hetero-carbonyl–ene reaction) can be performed with good reactivity and excellent enantioselectivity by virtue of the dual ...

Self-association of a naphthalene-capped-β-cyclodextrin through cooperative strong hydrophobic interactions
(Elsevier, 2011-09-05)
NMR, circular dichroism and fluorescence techniques were used to study the structure in solution of a new β-cyclodextrin derivate in which naphthalene chromophore group is bridged to O(2) and O(3) secondary positions of ...

Bicyclic (galacto)nojirimycin analogues as glycosidase inhibitors: Effect of structural modifications in their pharmacological chaperone potential towards β-glucocerebrosidase
(Royal Society of Chemistry (Great Britain), 2011)
A molecular-diversity-oriented approach for the preparation of bicyclic sp2-iminosugar glycomimetics related to nojirimycin and galactonojirimycin is reported. The synthetic strategy takes advantage of the ability of ...

Isolation and X-ray characterization of palladium-N complexes in the guanylation of aromatic amines. Mechanistic implications
(2013)
In the context of palladium-catalyzed guanylation of anilines herein, we have been able to characterize and isolate bis(anilino) and bis(guanidino)Pd(II) complexes using reaction conditions under which stoichiometric ...
