Evaluation of nitroalkenes as nitric oxide donors

Bioorganic & Medicinal Chemistry Letters, 2007
Chemiluminescence experiments demonstrate that simple nitroalkenes release low levels of nitric oxide. UV and EPR measurements suggest but cannot confirm direct NO release from nitroalkenes. Given the biological activity of nitrated unsaturated fatty acids, these results suggest the possible metabolic conversion of nitroalkenes to NO.

Nitroalkenes

2009
The literature up to July 2008 dealing with catalytic enantioselective FC alkylation of aromatic compounds with nitroalkenes has been reviewed. Both metal-mediated and organocatalysis have been employed leading to a vast array of enantiomerically pure compounds most of them of interest in medicinal chemistry.

Catalytic Asymmetric β‐Peroxidation of Nitroalkenes

Advanced Synthesis & Catalysis, 2008
AbstractThe first example of an asymmetric β‐peroxidation of nitroalkenes is disclosed. The reaction is promoted by catalytic loadings of a commercially available diaryl‐2‐pyrrolidinemethanol derivative and tert‐butyl hydroperoxide as the oxidant. A synthetically useful class of peroxides is obtained in good yield and enantioselectivity (up to 84% ee).

Chemoselective synthesis of functionalized conjugated nitroalkenes

The Journal of Organic Chemistry, 1992
The present one-pot methodology to obtain conjugated nitroalkenes from aldehydes and nitroalkanes is mild, and highly selective, and proceedsin good yields also on a large scale.

Solvent-free aziridination of α-nitroalkenes

Tetrahedron, 1998
Abstract NsONHCO 2 Et in the presence of CaO reacts without solvent with α-nitroalkenes to give 1-(ethoxycarbonyl)-2-nitroaziridines (62–84%). A possible involvement of an aza-Michael route is proposed on the basis of regio- and stereochemical reaction outcome, compared also with the results of thermolysis of ethyl azidoformate on the same α ...

A convenient procedure for the conversion of (E)-nitroalkenes to (Z)-nitroalkenes via erythro-β-nitroselenides

J. Chem. Soc., Chem. Commun., 1987
erythro-Selective conjugate addition of benzeneselenol to (E)-nitroalkenes and subsequent syn-elimination of benzeneselenenic acid provide a new method for the conversion of (E)-nitroalkenes into (Z)-nitroalkenes.

Selected reductions of conjugated nitroalkenes

Tetrahedron, 1990
Conjugated nitroalkenes are readily reduced by a variety of borane and borohydride reagents. The reactions provide a convenient access to a number of nitrogen and oxygen based functional groups.
