O (19.44 g, 71.9 mmol) was dissolved in water (50mL) and 2-naphthol (5.18 g, 35.9 mmol) was added to the solution at 50-60o
C for 1.5-2 h. The solvent was removed by suction filtration, and the precipitate washed with water. Then, residue was dissolved in CHCl3
(100 mL) and partitioned between water and CHCl3
. The organic layer was dried over anhydrous MgSO4
. The solvent was removed under reduced pressure and the residue was recrystallized from acetone/toluene.The yield is 83% as a yellow solid.

system at 70o
C for 1 h. Then, compound (S)-(-)-38a or (S)-(-)-38b ((S)-(-)-38a: 1.70 g, 2.2 mmol; (S)-(-)-38b: 1.52 g, 1.8 mmol) was added to the solution at 70o
C for 2 days. Then a small amount of 10% HCl was added to quench the reaction. The solvent was removed under reduced pressure, and the residue was partitioned between water and CH2
Cl2
. The organic layer was dried over anhydrous MgSO4
. The crude material was purified over silica gel column elutiong with hexane/ethylacetate ((S)-(-)-42a: v/v = 15/1;(S)-(-)-42b: v/v = 2/1) to give the compound (S)-(-)-42a or (S)-(-)-42b ((S)-(-)-42a: 0.81g, 50%; (S)-(-)-42b: 1.12g, 60%) as a white solid.

The solvent was removed under reduced pressure, and the crude in water was partitioned between 10%
HCl (50 mL) and CH

Cl2
. The organic layer was dried over anhydrous MgSO4
. The crude material was purified over silica gel column elutiong with hexane/acetone (v/v = 1/3) containing increasing amounts of CH3
OH from 0 to 50%) to give the compound (S)-(-)-49a or (S)-(-)-49b ((S)-(-)-49a: 87 mg, 90%; (S)-(-)-49b 88 mg, 91%) s a white solid.149
