SYNTHESIS OF SOME NOVEL α,β-ETHYLENIC SULFONES

Reddy, M. V. Ramana,Vijayalakshmi, S.,Reddy, D. Bhaskar,Reddy, P. V. Ramana

, p. 209 - 214 (2007/10/02)

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. Key words: Configuration, Knoevenagel condensation, sulfonylacetic acids, unsaturated sulfones.
