A Convenient Samarium-Promoted Synthesis of Aliphatic (E)-Nitroalkenes under Mild Conditions^†

, 2016
A samarium-promoted synthesis of (E)-nitroalkenes from 1-bromo-1-nitroalkan-2-ols in high yields and with total selectivity is reported. This reaction together with the easy and efficient preparation of the 1-bromo-1-nitroalkan-2-ols constitutes a simple

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

Part II: Nitroalkenes in the synthesis of heterocyclic compounds

, 2014
This part (part II) is devoted to 6-membered heterocycles that are synthesized from nitroalkenes as the key substrates. These compounds can be simply accessible to form nitroalkenes and C, O, N or S-nucleophiles bearing a suitable leaving group via 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).
