Abstract

Aminocyclopropanes equipped with pendant nucleophiles undergo C-C bond activation triggered carbonylative heterocyclization to provide 8-membered N-heterocycles. In these processes, intramolecular “capture” of a rhodacyclopentanone intermediate by an aryl or N-based nucleophile is followed by C-C or C-N bond forming “collapse” to the targets. These studies demonstrate how the combination of cyclopropane strain release and the templating effect of catalytically generated metallacycles can be harnessed to enable otherwise challenging medium ring closures.
