实验步骤: A solution of 1-azabicyclo[3.2.2]nonan-4-one (1.39 g, 10 mmol) in anhydrous tetrahydrofuran (20 mL) under nitrogen was cooled (-65° C.), and treated with n-butyl nitrite (1.30 mL, 11 mmol). 1.0N Lithium bis(trimethylsilyl)amide/THF (16 mL, 16 mmol) was added dropwise so as to keep the pot temperature below -58° C. After the addition was complete the mixture was warmed to room temperature over one h, stirred for 30 min, cooled on an ice bath, and treated with saturated ammonium chloride (6 mL). The solution was concentrated in vacuo, diluted with toluene, and reconcentrated to remove most of the water. The residue was chromatographed on silica gel (eluted with 5% methanol/methylene chloride, then with 10% methanol/methylene chloride), then triturated from ether to afford 1-azabicyclo[3.2.2]nonan-3,4-dione-3-oxime (0.92 g, 55%) as a white solid. the pot temperature below -58° C After the addition cooled on an ice bath The solution was concentrated in vacuo diluted with toluene to remove most of the water The residue was chromatographed on silica gel ( eluted with 5% methanol/methylene chloride with 10% methanol/methylene chloride), then triturated from ether
