Various novel β-diketones and β-ketoesters (4a-e) have been prepared by the condensation of 4-methyl sulphonyl benzoyl methylene bromide (2) with β−diketones and β-ketoesters (3a-e) in the presence of sodium methoxide in dry toluene. The structure of newly synthesized compounds have been elucidated by elemental analysis, IR, 1 H NMR and 13 CNMR studies.
