A hybrid phosphorus ligand for highly enantioselective asymmetric hydroformylation.
نویسندگان
چکیده
A new hybrid phosphorus ligand has been prepared starting from chiral NOBIN (2-amino-2'-hydroxy-1,1'-binaphthyl). Excellent enantioselectivities (up to 99% ee) have been achieved in the Rh-catalyzed asymmetric hydroformylations of styrene derivatives and vinyl acetate.

متن کاملSynthesis of triphosphorous bidentate phosphine-phosphoramidite ligands: application in the highly enantioselective hydrogenation of ortho-substituted aryl enamides.
The development of new effective chiral ligands is fundamental to asymmetric hydrogenation. Over recent decades, many excellent bisphosphine ligands have been reported for highly enantioselective hydrogenation reactions. However, the modification of a desired structural motif of most bidentate ligands is impeded by multistep synthesis. Recently, this situation has been partially remedied by the...

Synthesis of enantiomerically pure isoxazolidine via an asymmetric 1,3- dipolar cycloaddition reaction of nitrone with electron-deficient dipolarophile was described. The process occurs at room temperature in aqueous ethanol as a green solvent and in the presence of a bidendate bis(imine)–Cu(II)triflate complex as catalyst. The reaction mechanism is discussed on the basis of the assignment of t...
متن کاملRhodium/phospholane-phosphite catalysts give unusually high regioselectivity in the enantioselective hydroformylation of vinyl arenes.
Using the phospholane-phosphite ligand, BOBPHOS, almost perfect regioselectivities and high enantioselectivities (up to 92% ee) are observed in Rh catalysed enantioselective hydroformylation of vinyl arenes. This can be achieved under solvent-free conditions.
