A Rh-catalyzed domino conjugate addition-arylation sequence via a Rh(III) intermediate is reported. This process involving a proposed intramolecular oxidative addition of a rhodium enolate was utilized to achieve the synthesis of 3-substituted oxindole derivatives in moderate to excellent yields.

The intramolecular cyclisation of aryl radicals onto a pyrrole is studied. The cyclisation allows the synthesis of either the spiropyrrolidinyloxindole or the pyrrolo[3,2-c]quinoline skeleton depending on the nature of the protecting group at the N-pyrrole atom. The regiochemistry of the cyclisation is not affected by the substituents on the benzene ring. Some limitations on the utility of tosylmethyl-isocyanide in pyrrole synthesis are also reported.
