Abstract :
A hydroxyapatite-bound La complex, which functioned as an efficient heterogeneous catalyst for the Michael reaction of 1,3-dicarbonyls with enones under aqueous or solvent-free conditions, was prepared using a cation-exchange method. Further application to an asymmetric version by a fluoroapatite-bound La complex catalyst modified with (R,R)-tartaric acid is also described.
