Reaction Steps

A solution of 4-hydroxy-pentanoic acid methoxy-methyl-amide (0.12 g, 0.74 mmol) in tetrahydrofuran (1 mL) was cooled to −78° C., after which a solution of hex-1-ene-magnesium bromide (7.0 ml, 1.56 mmol) was added dropwise. After stirring at −78° C. for 2 hours, saturated ammonium chloride (2 mL) was added, and the reaction mixture allowed to warm to room temperature. Extraction and chromatography afforded 2-hydroxy-dec-9-en-5-one as a clear oil (33 mg).
