Cyclopropenones for Metabolic Targeting and Sequential Bioorthogonal Labeling

Cyclopropenones are attractive motifs for bioorthogonal chemistry, owing to their small size and unique modes of reactivity. Unfortunately, the fastest-reacting cyclopropenones are insufficiently stable for routine intracellular use. Here we report cyclop

Ligand-Enabled, Copper-Catalyzed Regio- and Stereoselective Synthesis of Trialkylsubstituted Alkenylboronates from Unactivated Internal Alkynes

We report the first copper-catalyzed regio- and stereoselective borylalkylation of dialkylsubstituted internal alkynes with bis(pinacolato)diboron and alkyl halides. A catalytically generated borylcopper species containing a novel π-accepting N-heterocycl

Oxygenated Metabolites of n-3 polyunsaturated fatty acids as potential oxidative stress biomarkers: Total synthesis of 8-F3t-IsoP, 10-F 4t-NeuroP and [D4]-10-F4t-NeuroP

A wide variety of metabolic products of polyunsaturated fatty acids is of paramount importance for improving our medical knowledge in the field of oxidized lipids. Two novel metabolites of n-3 polyunsaturated fatty acids, 8-F3t-IsoP and 10-F4t-NeuroP as well as a deuterated derivative thereof were synthesized based on an acetylenic intermediate. An original approach achieved lateral chain insertion of 8-F3t-IsoP by a ring-closing alkyne metathesis/semi-reduction strategy together with a temporary tether. Three for the price of one! Two strategies, Caruso coupling or ring-closing alkyne metathesis (RCAM), enabled the synthesis of 8-F 3t-IsoP and 10-F4t-NeuroP and its deuterated derivative from acetylenic intermediateA (see scheme). Such compounds represent potential biomarkers of neuronal oxidative stress.
