Technical Notes:
1.Michael Addition to promote enantioselective Michael re action between 1 ,3-dicarbonyl compounds and nitroolefins.
2.Spirocyclopentaneoxindoles with four contiguous stereocenters including one spiroquaternary stereocenter are synthesized by a combined Ru-catalyzed cross-metathesis/organocatalyzed asymmetric double-Michaeladdition.
3.Catalytic enantioselective conjugate addition reaction of a-fluoro-ß-ketoesters to nitroalkenes .
4.Catalytic enantiosele ctive electrophilic a-hydrazination promoted by chiral bifunctional organocatalysts .
5.Catalytic enantioselective Mannich reaction promoted by chiral bifunctional organocatalysts.
