title: Synthesis and biological activity of a new class of sulfone-linked pyrrolylpyrazoles and pyrrolylisoxazoles from methyl-3-aryl-2-(E-arylethenesulfonyl)acrylate.
abstract: A new class of sulfone-linked bis heterocycles, methyl-3-(4'-aryl-1'H-pyrazol-3'-ylsulfonyl)-4-aryl-3H-pyrrole-3-carboxylate (8), methyl-3-(1'-phenyl-3',5'-diaryl-1'H-pyrazol-4'-ylsulfonyl)-4-aryl-3H-pyrrole-3-carboxylate (9) and methyl-3-(3',5'-diarylisoxazol-4'-ylsulfonyl)-4-aryl-3H-pyrrole-3-carboxylate (10) were prepared by the regioselective reaction of methyl-3-aryl-2-(E-arylethenesulfonyl)acrylate (2) with tosylmethyl isocyanide followed by fuctionalization of olefin moiety with 1,3-dipolar reagents. The lead compounds were tested for their antimicrobial activity.
