1 H NMR and X-Ray Crystallographic Studies of p-Toluenesulfonamides of 2,5-Di(pyrrol-2-yl)pyrrolidines

Some pyrrole-N-substituted derivatives of cis-1-(4-methylphenylsulfonyl)-2,5-di(pyrrol-2-yl)pyrrolidine are prepared, subjected to Vilsmeier formylation and bromination conditions, and products characterised by NMR and in two cases X-ray analysis.
