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. |
