Synthesis of multicyclic β-Lactam derivatives via solid-phase- generated ketenes
(American Chemical Society, 2010-09)
An efficient approach for the solid-phase synthesis of multicyclic â-lactam derivatives is described. The key step is the cycloaddition reaction between an immobilized ketene and different cyclic imines to afford the ...
Ionic liquids as phase transfer catalysts: enhancing the biphasic extractive epoxidation reaction for the selective synthesis of β-O-glycosides
(Pergamon-Elsevier Science Ltd, 2017-08)
Ionic liquids promoted the direct epoxidation of glycals acting as PTC. 1,2-anhydrosugars were prepared by the oxidation of glycals under biphasic conditions with dimethydioxirane generated in situ from oxone/acetone and ...
Beta decay rates evaluated within the Gross Theory using experimental data for the Gamow-Teller resonance parameter
(Sociedade Brasileira de Física, 2020-06)
We improve the results for the β−-decay rates obtained within the context of the Gross Theory of Beta Decay (GTBD) by using new values of the parameter σN related to the standard deviation for the Gamow-Teller resonance: ...
Molecular diversity by olefin cross-metathesis on solid support. Generation of libraries of biologically promising β-lactam derivatives
(Molecular Diversity Preservation International, 2018-05)
The application of the reagent-based diversification strategy for generation of libraries of biologically promising β-lactam derivatives is described. Key features are the versatility of the linker used and the cross-metathesis ...
Investigation of the Effect of Tarantula cubensis Extract on Acute Phase Response
(Universidade Federal do Rio Grande do Sul, 2016)
Combining data from high-energy p p -reactions and neutrinoless double-beta decay: Limits on the mass of the right-handed boson
(World Scientific, 2016-10)
From the recently established lower-limits on the nonobservability of the neutrinoless double-beta decay of 76Ge (GERDA collaboration) and 136Xe (EXO-200 and KamLAND-Zen collaborations), combined with the ATLAS and CMS ...
