The title compound (R)-3,3'-bis(benzyloxymethyl)-1,1'-bi-2,2'-naphthol (R)-3 has been synthesized through the deprotection of MOM group by iprOH/HC1 in 83% isolated yield and the suitable single crystals for X-ray diffraction were obtained by recrystallization at room temperature from the mixture solvents. Crystallographic data for (R)-3: C36H30O4, Mr = 526.60,triclinic, space group P1, a = 10.057(6), b = 11.934(7), c = 12.314(6) (A), α = 85.52(2), β =70.245(13), γ = 76.554(11)°, Z= 2, V= 1352.8(13) (A)3, Dc = 1.293 g/cm3, F(000) = 556, R = 0.0745,wR = 0.1933 and μ(MoKα) = 0.083 mm-1. The title compound (R)-3 was found to be effective in the enantioselective addition of diethylzinc to aldehydes both in the presence and absence of Ti(OiPr)4. In the latter case, (R)-3 showed much higher catalytic activity and enantioselectivity than (R)-BINOL's.
