Aziridination of Conjugated Nitroalkenes
Tetrahedron Letters, 1997 Abstract The recently proposed amination methodology based on solid bases induced decomposition of arenesulphonyloxycarbamates (ArSO 3 NHCO 2 Et) has been applied to α-nitroalkenes. α-Nitroaziridines have been obtained in high yields and purity, under mild conditions.

, 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.

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 ...

Evaluation of nitroalkenes as nitric oxide donors
Bioorganic and Medicinal Chemistry Letters, 2007Chemiluminescence 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.

Enantioselective hydroxylation of nitroalkenes: an organocatalytic approach
Chemical Communications, 2007 An easy hydroxylation of aliphatic nitroalkenes in high yields and enantioselectivities is catalysed by bifunctional thiourea-cinchona alkaloids giving access to optically active nitroalcohols and aminoalcohols as final products.

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.

Catalytic Asymmetric β‐Peroxidation of Nitroalkenes
Advanced Synthesis and Catalysis, 2008AbstractThe 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).
