Heterocyclic sulfones IV:1-3 a novel synthesis of pyrrole and fused heterocyclic sulfones

The applicability and synthetic potency of the reagent diethyl 2-aryl-3-phenylsulfonylpropen-1,1-dicarboxylate 3 is reported. Compound 3 proved to be a key precursor in heterocyclic sulfones synthesis. Chemical and spectroscopic evidences for the structure of the newly synthesized compounds are described.

Studies with phenylsulfone derivatives: Synthesis of pyrrole, thiophene and their fused derivatives

(Chemical Equation Presented) 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.
