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.

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.

The addition of ethylenedinitrodiamine to nitroalkenes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1962
1. For the first time it was shown possible to add N-nitroamines to nitroalkenes, using the addition of ethylenedinitrodiamine to 1-nitrobutene-1 and 1-nitropentene-1 as an example, resulting In the formation of tetranitrodiazalkanes.

Nucleophilic Pentafluorophenylation of Nitroalkenes

Synthesis, 2012
The interaction of pentafluorophenylmagnesium bromide with conjugate nitroalkenes is described. The optimized conditions involve performing the reaction either in diethyl ether in the presence of chlorotrimethylsilane or in a tetrahydrofuran–diethyl ether solvent mixture.

Reaction of isonitrile with nitroalkene

Tetrahedron, 1972
Abstract The novel reaction of isonitrile ( 2 ) with nitroalkene ( 1 ) to produce isocyanate and α-cyano-α-substituted acetamide ( 3 ) is described. This involves the oxidation of 2 with 1 . In the reaction of 1b and 2b , the primary product 3bb further reacted with 1b to give the Michael adduct 4bb .

Catalytic Enantioselective Additions of Indoles to Nitroalkenes

Journal of the American Chemical Society, 2008
A new design principle that provides access to more active thiourea catalysts is described. Highly enantioselective additions of indoles to nitroalkenes are reported using a new quinolinium thioamide catalyst.
