Optically active (R,R,R)- and (R,S,R)-1,1':5',1" :5",1"'-quaternaphthalene-
2,2',6',2",6",2" '-hexol (QUANOL) were prepared from (R)-BINOL in five step
s. 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 th
e A value was not observed. Other basic properties for the use of QUANOL as
a chiral ligand are also reported.
