Several chiral aryl diphosphite ligands derived from pyranoside backbones of glucose and galactose were applied in Rh-catalyzed asymmetric hydroformylation of styrene.

Rhodium complex in situ formed by (R)PPhos (4,4',6,6'tetramethoxy2,2'bis(diphenylphosphino)1,1'bipyridine) with the available rhodium precursors are used for the asymmetric hydroformylation of styrene.

Their applications in the asymmetric hydroformylation and asymmetric conjug ed addition of diethylzinc to enones were investigated.

Study on application of asymmetric hydrogenation by chiral phosphorous ligand catalyst;

Synthesis and Asymmetric Hydrogenation of Novel Cyclic Enamides: (Z)-3-Arylidene-4-acyl-3, 4-dihydro-2H-benzoxazines;

Trans-cyclohexane-backbone iridium complexes with different axial chirality were synthesized from(1R,2S)-2-(pyridin-2-yl)cyclohexanol,and their application in asymmetric hydrogenation of(2H-chromen-3-yl)methanols was investigated.

The research progress in enantioselective hydrogenation catalyzed by heterogeneous catalysts is reviewed.

Recent progress in catalytic asymmetric hydrogenation of β-aminoacrylic acid ester derivatives is described, and various effects in the reactivity and enantioselectivity of hydrogenation reactions are discussed.

Induced by a small amount of chiral catalysts, H_2 is added to the unsaturated double bond, and the chiralmolecule is efficiently obtained in this catalytic asymmetric hydrogenation.

In this paper, reduction of imine compounds via asymmetric hydrogenation and hydrosilylation are introduced from metal center composing catalyst point of view, including the following three aspects, named titanocene-cata-lyzed system, Rh-andIr -catalyzed system, and Ru catalyzed system.
