To a stirred solution of benzeneruthenium (II) chloride dimer (3.10 mg, 0.006 mmol) and (1S, 2R)-(−)-cis-1-amino-2-indanol (3.7 mg, 0.025 mmol) in degassed isopropanol was heated at 80° C. for 20 minutes under argon. The mixture was added to the solution of 8-amino-3,4-dihydro-1H-naphthalen-2-one (50 mg, 0.310 mmol) in isopropanol (3 mL) at room temperature. A solution of potassium hydroxide (3.48 mg, 0.062 mmol) in isopropanol (1 mL) was added, and the mixture was stirred at 45° C. for 1 hour. The mixture was passed through silica gel and washed with ethyl acetate. The filtrate was concentrated under reduced pressure to afford the chiral 8-amino-1,2,3,4-tetrahydro-naphthalen-2-ol enantiomer (33.0 mg, 65% yield).
