In a follow-up paper, allylic amines were used and gave products of a rearrangement / intramolecular Diels-Alder cascade. Mechanistic details were also discussed, however further investigations in collaboration with the Houk group revealed an unusual and unexpected mechanism based on computational studies.
In a subsequent investigation, allylic amines produced rearrangement / intramolecular Diels-Alder cascade products. Mechanistic details were also considered; however, further collaborative work with the Houk group identified an unusual and unexpected mechanism through computational analysis.
