Water → 3-[Hydroxy(3-methoxyphenyl)methyl)-2-oxotetrahydrofuran

Participants

Reaction Steps

To a solution of y-butyrolactone (3.0 g) in tetrahydrofuran (THF) (30 ml) was added lithium diisopropylamide (LDA) (28 ml, 1.5 M solution in cyclohexane) at −78° C. under N2, and then after 30 minutes, a solution of m-anisaldehyde (4.7 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 3-[hydroxy(3-methoxyphenyl)methyl)-2-oxotetrahydrofuran (7.4 g).
