Abstract

Novel unsaturated sulfones E-alkoxy/carbamoyl benzyl styryl sulfones (VI) and E-4(N-benzylcarbamoyl)benzyl styryl sulfones (IX) have been prepared by the Knoevenagel condensation of alkoxy/ carbamoyl benzylsulfonylacetic acid (V) and 4-carboxybenzylsulfonylacetic acid (VIII) with araldehydes. The E-geometry of these compounds has been assigned based on IR and ¹H NMR spectral data.
