To a solution of vinyl acetate (150 mL) of racemic cyclohexenol derivative (±)-6 (14.0 g, 82.5 mmol) was added P. stutzeri lipase (Meito TL) (1.40 g), and the reaction mixture was stirred vigorously for 40 h at room temperature. After filtration of the lipase, the volatile organic compounds were removed under reduced pressure and the remaining materials were purified by flash column chromatography (ethyl acetate:hexane=1:3-1:1) to afford (+)-6 (6.75 g, 49%, 99% ee) and (-)-7 (8.25 g, 48%, 96% ee).
