Unique Ionic Iodine Atom Transfer Cyclization: A New Route to Iodomethylated Pyrrolidine Derivatives from γ-Iodoolefin and Chloramine-T
摘要:
[GRAPHIC]Pyrrolidines and bicyclic pyrrolidine derivatives can effectively be synthesized from gamma-iodoolefins using commercially available chloramine-T (CT) as a nitrogen source. The cyclization proceeds with high stereoselectivity via a cyclic iodonium intermediate.
