SYNTHESIS OF CHIRAL DEPSIPEPTIDE BUILDING BLOCK BY THE ASYMMETRIC REDUCTION OF N-(α-KETOACYL)-α-AMINO ESTERS

Asymmetric reduction of N-(α-ketoacyl)-α-amino esters was performed by using homogeneous hydrosilylation and hydrogenation catalyzed by rhodium(I) complexes.The asymmetric hydrosilylation achieved good to high stereoselectivities giving the corresponding

Preparation of optically active peralkyldiphosphines and their use, as the rhodium(I) complex, in the asymmetric catalytic hydrogenation of ketones

Two types of the optically active peralkyldiphosphine, 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis(dialkylphosphino)butane (Rdiop 3) and N-(N'-substituted carbamoyl)-4-dicyclohexylphosphino-2-dicyclohexylphosphinomethylpyrrolidine (R-Cycapp 8), have been p
