We reported that the formation of these compounds can be carried out starting with allylic amines (4-endo mode cyclizations) using bis(collidine)bromonium(I) hexafluorophosphate as an electrophile. These cyclizations occur via a carbocation intermediate. Citing Literature Volume2000, Issue17September 2000Pages 3007-3011 RelatedInformation
