Copper-catalyzed Z-selective synthesis of acrylamides and polyacrylamides via alkylidene ketenimines
Nature Communications, 2022 Alkylidene ketenimines are rarely reported, but synthetically useful, reactive intermediates. Here, the authors disclose a three-component reaction of alkyne, azide and water by cycloaddition, nitrogen extrusion, and carbene-assisted rearrangement, via ...

Beilstein Journal of Organic Chemistry, 2020 New synthetic methods for spirolactams bearing an α-methylene-γ-butyrolactone or its analogous methylene-lactam have been developed. The allylation of γ-phenylthio-functionalized γ-lactams with 2-(acetoxy)methyl acrylamides was accomplished by using 2.5 ...

A Recyclable Nanoparticle-Supported Rhodium Catalyst for Hydrogenation Reactions
Molecules, 2010 Catalytic hydrogenation under mild conditions of olefins, unsaturated aldeydes and ketones, nitriles and nitroarenes was investigated, using a supported rhodium complex obtained by copolymerization of Rh(cod)(aaema) [cod: 1,5-cyclooctadiene, aaema ...

Die Umlagerung der Addukte von Säuren an Push-Pull-Acetylene : Ihre Anwendung in der Peptid-Synthese
CHIMIA, 1979 Push-pull-acetylenes (1) react rapidly and smoothly with proton acids to yield 3-dialkylamino-3-X-acrylic derivatives, which rearrange under very mild conditions (and in the case of the adducts of carboxylic acids quantitatively) to 3-X-N,N-dialkyl ...

Bile Acid Sequestrants Based on Natural and Synthetic Gels
Gels, 2023 Bile acid sequestrants (BASs) are non-systemic therapeutic agents used for the management of hypercholesterolemia. They are generally safe and not associated with serious systemic adverse effects.

Molecular Oncology, EarlyView.Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
