Red-Light-Induced nPr-DMQA+-Catalyzed [3+2] Cycloaddition of Cyclopropylamines with Alkenes or Alkynes

Abstract

A red-light-mediated [3+2] annulation of cyclopropylamines with akenes or alkynes in the presence of nPr-DMQA+ has been reported. An array of cyclopentane or cyclopentene derivatives with diverse functional groups have been obtained in moderate to excellent yields under mild conditions
