A base-promoted oxidative dearomatization of substituted pyrroles for the synthesis of 3,3-disubstituted 4-pyrrolin-2-ones under mild reaction conditions is described. A cascade aerobic oxidation/semipinacol rearrangement reaction was involved, and the desired products bearing a quaternary carbon center were efficiently prepared using molecular oxygen (O2) as an ideal oxidant.

Reactivity of phenyllithium with a number of succinimide derivatives were studied. We have shown that the Thorpe-Ingold effect affected both the reaction products distribution and their structures. Regioselectivity of these reactions were rationalized. Structures were confirmed with NMR and crystallographic methods.
