Reverse Cope elimination reactions. 2. Application to synthesis
摘要:
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.

[reaction: see text] Neutral scandium amido complexes are viable catalysts for intramolecular alkenehydroamination. Catalytic activity is strongly coupled to the electronic character of the Sc(III) ligand environment with chelating diamide coordination providing a precatalyst possessing substantially improved activity and superb distereoselectivity in the synthesis of trans-2,5-disubstituted pyrrolidines
