摘要: A review into the aza-Diels–Alder reaction, mainly concentrating on literature examples that form piperidin-4-ones from reaction of imines and electron rich dienes or enones, either through a Lewis acidic/Bronsted acid approach use an organocatalyst. This questions whether mechanism is step wise as opposed to concerted when using oxygenated dienes.
