Unveiling the intramolecular [3 + 2] cycloaddition reactions of<i>C</i>,<i>N</i>-disubstituted nitrones from the molecular electron density theory perspective

Abstract

The zwitterionic type intramolecular [3 + 2] cycloaddition reactions of nitrones show remarkable substituent effects and varying reactivities in the cases of cyclic and acyclic alkenes.
