【摘要】：正Chiral phosphorus ligands play a vital role in the development of transition metal catalyzed asymmetric synthesis, and many highly enantioselective chiral phosphorus ligands have been synthesized in past few decades. Recently, we developed two types of chiral phosphorus ligands containing l,l'-spirobiindane and 1,9' -spirobifluorene backbones from enantiomerically pure 1,1' -spirobiindane-7,7' -dioland 1,9' -spirobifluorene-1,1'-diol. The monodentate spi-
