REVERSE COPE ELIMINATION-REACTIONS .2. APPLICATION TO SYNTHESIS(1)

Intramolecular addition of N,N-disubstitute hydroxylamines to unactivated olefins was used to prepare an indolizine, a pyrrolo[2,1-a]isoquinoline, a 1,8-diazaspiro[4.5]decane, a cyclopenta[b]pyrrole, and an isoindoline. A pyrrolizine and a 1-azabicyclo[2.2.1] heptane were synthesized from acyclic precursors by two consecutive reverse Cope elimination reactions.
