YieldReaction ConditionsOperation in experiment
39%; 37% To a solution of rac-2 (5.7 g, 20 mmol) in anhydrous acetone (100 mL), was added N-benzylcinchonidinium chloride (N-BC; 5.0 g, 12 mmol). The reaction mixture was refluxed for 12 h, and then cooled to 25 C. The resulting molecular complex of (R)-2-N-BC was collected by filtration, and then was washed with acetone (30 mL). The mother liquid was evaporated under reduced pressure to yield the enriched (S)-2. The (R)-2-N-BC was dissolved in 1N HCl (50 mL) and ethyl acetate (100 mL) by stirring for 10 min. The organic layer was washed with brine (20 mL) and dried over Na2SO4. After the solvent was evaporated under reduced pressure, the solid residue was recrystallized from benzene to afford (R)-2 (2.2 g, 39%). (S)-2 was extracted and purified using a similar method that described for (R)-2 (2.1 g, 37%). Enantiomeric purities were obtained by chiral HPLC (eluents: hexane:IPA = 80:20 v/v, flow rate: 1 mL min-1, monitoring wavelength: 256 nm). Each fraction at 11 min and 22 min was attributed to (R)-2 and (S)-2 with > 99% ee (Figure S1).

The reaction mixture was cooled to 25 C., and the resulting solid was washed with water and filtered.By recrystallizing the filtrate with benzene,Racemic 2-amino-2'-hydroxy-1,1'-binaphthyl (rac-NOBIN) and DBC were separated.The reaction yield was calculated by chiral HPLC. In addition, the isolation yield of the compound after recrystallization from benzene was calculated. These reaction yields and isolation yields are described in Table 1.
