    • General Procedure for the Synthesis of ω-Hydroxy Ketones from Lactones A slurry of lactone (1.0 mmol, HN(OMe)Me·HCl (116 mg, 1.2 mmol, and NaOMe (14 mg, 0.25 mmol) in THF (20 mL) was cooled with an ice-salt bath under nitrogen. A solution of Grignard reagent in THF (16 mL, 0.5 M, 8.0 mmol) was added slowly. After 2 h in an ice-salt bath the reaction mixture was allowed to warm to r.t. and stirred for 8 h. The reaction was quenched with 1 N HCl solution (10 mL, The mixture was stirred for another 2 h, and THF was evaporated. The residue was treated with H2O (20 mL) and then extracted with CH2Cl2. The organic extract was dried over MgSO4 and concentrated. The residue was purified by flash column chromatography on silica gel (EtOAc-PE) to give the desired hydroxy ketone
