    A simple, regioselective, convenient, and base mediated synthesis of (2E,4E)-5-aryl-6-oxo-6-phenyl-3-sec.amino-hexa-2,4-dienenitriles has been achieved by the reaction of 6-aryl-4-sec.amino-2-oxo-2H-pyran-3-carbonitriles and benzyl cyanide. This reaction involves ring opening of the pyran ring at the C6 position by benzyl cyanide followed by decarboxylation and regioselective oxidative decyanation

  • Synthesis of E - and Z -Pyrazolylacrylonitriles and their evaluation as novel antioxidants

    A facile synthesis of (Z)- and (E)-2-(5-arylpyrazol-3-yl)-3-(pyrrol-2-yl)acrylonitriles and (Z)-2-(1,3-diarylpyrazol-5-yl)-3-(pyrrol-2-yl)acrylonitriles, and isomerisation of (Z)-2-(5-arylpyrazolyl)acrylonitriles to (E)-2-(5-arylpyrazolyl)acrylonitriles under basic conditions have been reported. (Z)-2-(1,3-Diarylpyrazolyl)acrylonitrile did not undergo isomerisation under the similar conditions. New compounds were identified on the basis of their spectral data (H-1-, C-13-, H-1-H-1 COSY, NOESY, NOE, HMQC NMR, IR, UV and EI mass). The structures of one acrylonitrile and five of their precursor 6-arylpyran-2-ones and cyanomethylpyrazoles were confirmed by X-ray crystallographic studies. Effects of pyrazolylacrylonitriles and their precursors on rat liver-microsomal lipid peroxidation were evaluated in vitro with a view to establish structure-activity relationship and to identify a lead compound.

    simple, efficient and transition metal-free strategy was established for the synthesis of highly functionalized, sterically hindered allylarenes (6, 7 & 8) by base-mediated ring transformation of 2-oxo-6-aryl-4-(methylthio/sec-amino)-2H-pyran-3-carbonitriles (3/4) with 5-hexene-2-one (5). This provides a method for the synthesis of allylarenes functionalized with different electron donating and withdrawing
