A new approach to the synthesis of (±)-methyl jasmonate and (±)-baclofen via conjugated addition of oxazoline cyanocuprate to Michael acceptors

Journal of the Brazilian Chemical Society, 2001
Introduction of a synthon equivalent to a carboxymethyl anion to enones and nitroalkenes, through a 1,4-addition reaction of 2,4,4-trimethyl-2-oxazoline cyanocuprate 3, proved to be an interesting methodology for the synthesis of natural products such as

Assembly of fully substituted triazolochromenes via a novel multicomponent reaction or mechanochemical synthesis

Beilstein Journal of Organic Chemistry, 2018
A new metal-free one-pot three-component procedure towards fully substituted triazolochromenes has been developed, starting from commercially available materials. Salicylaldehydes and nitroalkenes were reacted under solvent-free conditions, followed by a

Betaketothioesters in organocatalysis: Harnessing nucleophilic reactivity, the fluorophobic effect, and expanding the substrate repertoire

Tetrahedron Chem
The use of thioesters as nucleophiles marks a considerable change in organic synthesis. This new method, propelled by gentle enolization with minimal catalyst loading, results in enantiomeric excesses surpassing 95 % under ambient conditions ...

Nitro-fatty acid signaling: Therapeutic potential in inflammatory diseases

Redox Biochemistry and Chemistry
This review explores the interaction between nitric oxide-derived reactive species and unsaturated fatty acids, leading to the formation of electrophilic nitroalkenes, named nitro-fatty acids (NO2-FA).

Single enantiomer propeller-shaped polynuclear complexes as catalysts-proof-of-concept for enantioinduction in a Michael addition reaction

Royal Society Open Science
We report a family of propeller-shaped polynuclear metal complexes whose overall chirality is dictated by a single stereogenic centre within their component amino alcohol-ligand.
