Niobium-based chiral Lewis acid was found to be highly effective catalyst for aza-Diels–Alderreactions of imines with Danishefsky‘s dienes. The reactions proceed in high yield with high enantioselectivity for both aromatic and aliphatic imines. The developed methodology was applied to total synthesis of (+)-anabasine.
