Bidentate Lewis acid catalysts in asymmetric synthesis*
The chemistry of bidentate Lewis acids belongs to an unexplored field of science, and so far has been only poorly studied. This paper illustrates the design of several bidentate Al and Ti Lewis acids, and their successful application to selective organic synthesis, particularly to asymmetric synthesis. For example, a new, chiral bidentate Ti(IV) complex is successfully designed by adding commer...
متن کاملTandem Reactions Combining Biocatalysts and Chemical Catalysts for Asymmetric Synthesis
The application of biocatalysts in the synthesis of fine chemicals and medicinal compounds has grown significantly in recent years. Particularly, there is a growing interest in the development of one-pot tandem catalytic systems combining the reactivity of a chemical catalyst with the selectivity engendered by the active site of an enzyme. Such tandem catalytic systems can achieve levels of che...

متن کاملBifunctional transition metal-based molecular catalysts for asymmetric syntheses.
The discovery and development of conceptually new chiral bifunctional transition metal-based catalysts for asymmetric reactions is described. The chiral bifunctional Ru catalyst was originally developed for asymmetric transfer hydrogenation of ketones and imines and is now successfully applicable to enantioselective C-C bond formation reaction with a wide scope and high practicability. The depr...
متن کاملAsymmetric Hydrogenation Catalysts
Iridium complexes with chiral N,P ligands have established themselves as efficient catalysts for the asymmetric hydrogenation of olefins, with largely complementary scope to Rh and Ru diphosphane complexes. In contrast to Rh and Ru catalysts, they do not require a coordinating polar group next to the C=C bond. Initial experiments with cationic phosphanyloxazoline (phox) complexes ([Ir(1)(cod)]X...
