Participants

Procedure

Sodium acetate (1.45 g, 17.7 mmol) and hydroxyl amine hydrochloride (0.68 g, 9.75 mmol) were added to a solution of 2,2a,7,7a-tetrahydro-cyclobuta[a]inden-1-one (1.4 g, 8.86 mmol) in MeOH (18 mL), and stirred overnight at room temperature. The reaction solution was concentrated via rotary evaporation. The residue was dissolved in CH2Cl2 (100 mL), washed with H2O (50 mL), dried over MgSO4, and concentrated to give the subtitle compound, which was used without further purification. MS calculated for C11H11NO+H: 174, observed: 174.
