Niobium-based chiral Lewis acid was found to be highly effective catalyst for aza-Diels-Alder reactions 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.
