Abstract
Abstract Enantioselective insertion reactions of methyl phenyldiazoacetate into the SiH bond of silanes were effected by employing dirhodium(II) carboxylates incorporating N -phthaloyl-( S )-amino acids as chiral bridging ligands. The use of dirhodium(II) tetrakis[ N -phthaloyl-( S )-phenylalaninate] as a catalyst produced methyl (2 S )-(dimethylphenylsilyl)phenylacetate in 74% ee, whereas catalysis with dirhodium(II) tetrakis[ N -phthaloyl-( S )-phenylglycinate] afforded its enantiomer in 72% ee.
