5-(Trimethylsilyl)furan-3-carbaldehyde → HCID 19886001, compound

Participants

Reaction Steps

A solution of 2-methoxyethoxymethyl tributylstannylmethyl ether (620 mg, 1.5 mmole) in tetrahydrofuran (THF) (5 ml) at -78° C. was treated with n-butyl lithium (92.5M solution in hexane: 0.67 ml, 1.67 mmole). After 10 min., a solution of 5-trimethylsilyl-3-furaldehyde (254 mg, 1.5 mmole) in THF (2 ml) was added. The solution was stirred for 3 hours while the cooling bath warmed to room temperature. The mixture was quenched with water and the aqueous phase extracted with ethyl ether. The combined organic portions were dried over MgSO4, filtered and concentrated. Purification by flash chromatography (silica, 50% ethyl ether/hexane) gave 216.5 mg of the title compound as a light yellow oil.
