The applicability and synthetic potency of the novel reagents diethyl 2-aryl-3-(phenylsulfonyl)propene-1,1-dicarboxylate 3 are reported. Compounds 3 are shown to be key precursors in heterocyclicsulfones syntheses. Chemical and spectroscopic evidence for the structure of the newly synthesized compounds are described.

Diethyl 2-(1-phenyl-2-(phenylsulfonyl)ethylidene)malonate 3 has been prepared via the reaction of 6 with sodium benzenesulfinate. Compound 3 proved to be highly reactive towards various reagents and underwent numerous chemical transformation, resulting in the construction of a wide range of heterocyclic sulfone systems.
