Allgemeine Beschreibung
trans-4-Methyl-β-nitrostyrene ((E)-1-methyl-4-(2-nitrovinyl)benzene) is a nitrolefin. Its asymmetric Michael addition with benzaldehyde in the presence of silylated pyrrolidine catalyst has been reported. Its hydrogenation in the presence of Pd(II) complexes of (Z)-2-((quinolin-3-ylimino)methyl)phenol as catalyst has been studied.
Anwendung
trans-4-Methyl-β-nitrostyrene may be used as a reagent in the synthesis of N-benzylpyrrolomorphinans and 4-oxo-2-aryl-4H-chromene-3-carboxylate derivatives.

A new method for the preparation of N-benzylpyrrolomorphinans has been developed. Thus Michael reaction of the benzylimines of oxycodones and oxymorphones with nitrostyrenes gave a series of 4'-aryl-N-benzylpyrrolomorphinans. These were selective delta antagonists of much higher in vitro potency (with

The unusual alcohol mediated formation of 4-oxo-2-aryl-4H-chromene-3-carboxylate (flavone-3-carboxylate) derivatives from 4-hydroxycoumarins and β-nitroalkenes in an alcoholic medium is described. The transformation occurs via the in situ formation of a Michael adduct, followed by the alkoxide ion mediated rearrangement of the
