Abstract
(1S,1'S,2R,2'R)-1,1'-Di-tert-butyl-2,2'-diphosphetanyl was prepared from tert-butylphosphine via phosphine-boranes as intermediates. The rhodium complex of the ligand was used as a highly efficient catalyst in asymmetric hydrogenations of α-acetyl-aminoacrylates and α-substituted enamides.
