Radical [3 + 2] Annulation of <i>N</i>-Allyl-<i>N</i>-chlorotosylamide with Alkenes via Atom-Transfer Process

Abstract

[reaction: see text]. A radical [3+2] annulation reaction with an N-centered radical has been developed. The reaction of alkenes with N-allyl-N-chlorotosylamide yields the corresponding pyrrolidine derivatives in good yields in the presence of Et3B as a radical initiator.
