An efficient method for the oxidation of aromatic sulfides has been developed by using aqueous H2O2, catalyzed by the in situ generated chiral Fe/6,6′-bis(4-isopropyloxazolin-2-yl)-2,2′-bipyridine (bipybox-iPr) complex. The corresponding sulfoxides were obtained with high enantioselectivities (up to 98.5:1.5 er) and in good yields (up to 61 %) when the mono-oxidation of the sulfides was performed in combination with the kinetic resolution of the sulfoxide into the sulfone.
Asymmetric hetero-Diels-Alder reaction of glyoxylate esters and Danishefsky's diene catalyzed by chiral bis(oxazoline)-lanthanide complexes

Asymmetric hetero-Diels-Alder reactions of glyoxylate esters and Danishefsky's diene catalyzed by various chiral bis(oxazoline)-lanthanide complexes afforded the corresponding aldol adducts, which upon treatment with trifluoroacetic acid, furnished the he
