With 5%-palladium/activated carbon; hydrogen In methanol; ethyl acetate for 16 h;
A mixture of l-(benzyloxy)-4-(hexyloxy)benzene (12.97 g) and 5percent Pd/C (1.2 g) in 200 mL of 1: 1 MeOH/EA was stirred under hydrogen for 16 hr. Starting material was consumed, as seen by TLC analysis. The reaction mixture was filtered through Celite, the solvents were exchanged to 12percent EA/Hex, and the mixture was filtered through a pad of silica gel and concentrated to give 8.84 g of 4-(hexyloxy)phenol. R 0.21 (10percent EA/Hex); 1H NMR (CDC13) δ 6.80-6.72 (m, 4H), 3.88 (t, 2H, J=6.7 Hz), 1.79-1.68 (m, 2H), 1.48-1.30 (m, 6H), 0.91- 0.86 (m, 3H).

4-(benzyloxy)benzoic acid (20.0 g, 87.6 mmol), 4-(hexyloxy)phenol (17.0 g, 87.6 mmol), N,N'-dicyclohexylcarbodiimide (21.7 g, 105 mmol) and 4-dimethylaminopyridine (535 mg, 4.38 mmol) were dissolved in 300 mL of methylene chloride. The resulting solution was stirred for 3 hours at room temperature. Then, 300 mL of pure water was added thereto, and then the resulting liquid was filtered to remove insoluble matters. Thereafter, the obtained solution was subjected to separation operation, and the resulting methylene chloride solution was washed with a saturated aqueous sodium chloride solution and dried over magnesium sulfate. After methylene chloride was distilled off, the resulting solid matter was washed with methanol. Thereby, a white solid compound, 4-(hexyloxy)phenyl 4-(benzyloxy)benzoate (24.9 g) was obtained.

With sodium hydroxide; In ethanol; at 50℃; for 15h;
General procedure: To a solution of 15 mmol of an appropriate phenol 3-3g in 9 mL of EtOH was added at stirring a solution of 0.72 g (18 mmol) of NaOH in 3 mL of water. The mixture was boiled at stirring for 2 h, cooled to 50C, and was added by portions a solution of 1.95 g (17.6 mmol) of rac- or (R)-3-chloropropane-1,2-diol in 3 mL of EtOH. The mixture was boiled at stirring for ~15 h. The reaction completion was fixed by TLC (Rf of reaction products ~0.2, eluent hexane-EtOAc, 6 : 4). On cooling the reaction mixture was diluted with water (70 mL), the reaction products were extracted with Et2O (3 × 60 mL). The combined extracts were washed with 1 M water solution of NaOH (15 mL) to remove phenol residues and dried with MgSO4. The solvent was removed in a vacuum. The crystalline residue was purified by column chromatography on silica gel (eluent hexane-EtOAc,8 : 2-4 : 6). The recrystallization was done from amixture hexane-EtOAc, 5 : 1. NMR spectra of obtained diols (R)-1-1g are identical to the spectra of racemic analogs.
