An air-stable P-chiral phosphine ligand for highly enantioselective transition-metal-catalyzed reactions.

J. Am. Chem. Soc. 127 , 11934, (2005)

A new P-chiral phosphine ligand, (R,R)-2,3-bis(tert-butylmethylphosphino)quinoxaline, has been prepared by the reaction of enantiomerically pure tert-butylmethylphosphine-borane with 2,3-dichloroquinoxaline. This ligand, in contrast to most of the previously ...
