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 another paper, allylic amines led to rearrangement / intramolecular Diels-Alder cascade products. The mechanisms were discussed as well, but additional investigations by collaboration with the Houk group uncovered an unconventional and unforeseen process based on computational studies.
