Page/Page column 42-43; 69-75, (2017/10/30)
D The present invention relates to ion pair catalysts (I) comprising the cationic bisguanidinium ligand (A) and diperoxomolybdate anion (B). The present invention also relates to ion pair catalysts (III) comprising the cationic bisguanidinium ligand (C) and peroxotungstate anion (D). It further relates to the use of the said catalysts in the manufacture of enantiomerically enriched sulfoxides.
3. Naphthopyranquinone Antibiotics: Novel Enantioselective Syntheses of Frenolicin B and Some of Its Stereoisomers

, p. 43 - 58 (2007/10/03)
Two new enantioselective syntheses of the naphthopyranquinone antibiotic frenolicin B (1), of its enantiomer 2, and of its diastereoisomers 3 and 4 were accomplished using two different routes from optically active β-hydroxy esters (R)- and (S)-11 and 18.
Asymmetric Periodate Oxidation of Functionalized Sulfides Catalyzed by Bovine Serum Albumin
Colonna, Stefano,Banfi, Stefano,Fontana, Francesca,Sommaruga, Maurizio
, p. 769 - 771 (2007/10/02)
The asymmetric oxidation of the functionalized sulfides with sodium metaperiodate in the presence of a catalytic amount of bovine serum albumin (BSA) affords the corresponding sulfoxides with enantiomeric excess (ee) up to 69.3percent.The influence of the
