Asymmetric IgG antibodies induced by different immunotherapies in a murine model of allergy
(Taylor & Francis, 2009-09)
Specific immunotherapy (SIT) is the only potentially curative treatment for those allergic processes mediated by IgE. We compared the effects of different SITs in mice sensitised with ovalbumin (OVA) Al (OH)3 : 1) OVA ...
Development of polymer-supported chiral aminoalcohols derived from biomass and their application to asymmetric alkylation
(Pergamon-Elsevier Science Ltd, 2016-05)
A synthetic strategy has been developed for the preparation of immobilized 1,2-aminoalcohols starting from easily available and renewable chiral building blocks. They were tested as chiral ligands for the asymmetric ...
New dinuclear asymmetric complexes of ruthenium and rhenium
(Taylor & Francis Ltd, 2001-04)
New dinuclear asymmetric complexes of ruthenium and rhenium, of formula [(bpy)(CO)3 ReI(4,4′bpy)RunII/III (NH3)5]3+/4+ have been prepared and characterized by spectroscopic and electrochemical techniques. In the mixed-valent ...
Asymmetric hydrogenation of 3,4-hexanedione over PtSn catalysts
(Springer, 2010-05-22)
In this work, some results of the liquid-phase racemic and enantioselective hydrogenation of 3,4-hexanedione are presented. The catalysts employed were platinum-based, supported on SiO2. Monometallic catalysts were modified ...
Synthesis of new chiral 1,3-aminoalcohols derived from levoglucosenone and their application in asymmetric alkylations
(Pergamon-Elsevier Science Ltd, 2015-05)
We have developed a simple procedure for the preparation of chiral 1,3-aminoalcohols using the biomass derivative levoglucosenone, as the chiral starting material. 1,3-aminoalcohols, bearing primary and tertiary amino ...
Coexistence of phases in asymmetric nuclear matter under strong magnetic fields
(IOP Publishing, 2015-08)
The equation of state of nuclear matter is strongly affected by the presence of a magnetic field. Here we study the equilibrium configuration of asymmetric nuclear matter for a wide range of densities, isospin composition, ...
Catalytic Asymmetric Synthesis and Stereochemical Revision of (+)-Cryptoconcatone H
(American Chemical Society, 2017-09)
The total synthesis and structural revision of (+)-cryptoconcatone H are described. Guided by computational studies for the final structure assignment, the stereogenic centers at the tetrahydropyran moiety of (+)-cryptoconcatone ...
Chiral Lewis acid catalysts in diels-Alder cycloadditions: mechanistic aspects and synthetic applications of recent systems
