ION PAIR CATALYSIS OF TUNGSTATE AND MOLYBDATE

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.

Diastereofacial selectivity in aldol-type condensation induced by optically pure α-sulfinyl acetate with α-substituted aldehydes

Highly diastereoselective aldol-type condensations induced by the chiral magnesium enolate of tert-butyl p-tolyl sulfinyl acetate were performed with optically pure alkyl or hydroxy α-substituted aldehydes. The addition of chiral α-sulfinyl acetate to var

3. Naphthopyranquinone Antibiotics: Novel Enantioselective Syntheses of Frenolicin B and Some of Its Stereoisomers

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 synthesis of 4-phenyl-1,5-diazacyclooctan-2-one using optically active vinyl sulfoxides

Both enantiomers of (S)- and (R)-4-phenyl-1,5-diazacyclooctan-2-ones (7) were synthesized stereoselectively with good optical purity by the asymmetric conjugate addition of pyrazolidine to optically active vinyl sulfoxides, t-butyl (E)-2-[(R)- and (S)-p-tolylsulfinyl]cinnamates, respectively. Starting from 7, a synthesis of optically active homaline was achieved.

Asymmetric Periodate Oxidation of Functionalized Sulfides Catalyzed by Bovine Serum Albumin

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
