Reaction Steps
To a solution of cyclooctanone (4.0 g) in THF (40 ml) was added LDA (23 ml, 1.5M solution in cyclohexane) at −78° C. under N2, and then after 30 minutes, a solution of m-anisaldehyde (4.1 g) in THF (10 ml) was added in the solution. After being stirred for 2 hours at the same temperature, the solution was poured into the mixture of ethyl acetate and water. The organic layer was washed with 1N-HCl solution, sat. NaHCO3, and brine, dried over MgSO4, and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 2-{hydroxy-(3-methoxyphenyl)methyl}cyclooctanone (6.9 g).
