C 2-Symmetric Bioxazolines and Bithiazolines as New Chiral Ligands for Metal Ion Catalyzed Asymmetric Syntheses: Asymmetric Hydrosilylation

All articles of this category New chiral C 2 -symmetric bioxazolines (4,4′ -disubstituted 4,5,4′ ,5′ -tetrahydro-2,2′ -bioxazoles) and bithiazolines (4,4′ -disubstituted 4,5,4′ ,5′ -tetrahydro-2,2′ -bithiazoles) obtained in a few simple steps from amino acids were found to induce up to 84% enantiomeric excess in the rhodium( I )-catalyzed asymmetric hydrosilylation of acetophenone.
