Abstract:
Optically active (R,R,R)- and (R,S,R)-1,1':5',1":5",1'"-quatemaphthalene-2,2',6',2",6",2"'-hexol (QUANOL) were prepared from (R)-BINOL in five steps. The CD spectrum of (R,R,R)-QUANOL showed a larger A value than those of (R)-BINOL and (R,S,R)-QUANOL, but additivity of the axial chiralities in the A value was not observed. Other basic properties for the use of QUANOL as a chiral ligand are also reported.
