实验步骤: Solid NaHCO3 (1.2 mol) and mCPBA (1 2 mmol, 77% purity) were added to a solution of ketone 1A (0.6 mmol) in DCM (5 mL) at 0° C. The reaction mixture was allowed to warm to rt and was maintained for 1 h. The reaction mixture was diluted with a saturated, aqueous solution of sodium bisulfate (10 mL) and was extracted with DCM (3×10 mL). The combined organic layers were dried (Na2SO4) and concentrated. The residue was purified by silica gel chromatography (10/90 to 30/70 EtOAc/hexane) to provide lactone 16A in 90% yield.

实验步骤: A solution of N-(4-oxoadamantan-1-yl)acetamide (1A) (20 mmol) in 200 mL of concentrated, aqueous HCl was heated in a sealed pressure tube at 130° C. for 20 h. The solvent was removed under reduced pressure to give amine 1B as an HCl salt in 90% yield as an off-white solid. Data: LC/MS (ESR) m/z 166 [M+1]+. The solvent was removed under reduced pressure

实验步骤: A stirred solution of 1-acetamido-4-oxoadamantane (420 mg, 2.0 mmol) in MeOH (20 mL) was cooled in an ice bath and an NaBH4 caplet (1.0 g, 26 mmol) was added. The mixture was stirred over the weekend at rt and evaporated to dryness. The residue was taken up in EtOAc (90 mL), washed with 5% aq HCl (20 mL) and satd aq NaHCO3 (20 mL), and dried over MgSO4. Removal of the solvent left 1-acetamido-4-hydroxyadamantane (170 mg, 40%). evaporated to dryness washed with 5% aq HCl (20 mL) dried over MgSO4 Removal of the solvent left 1-acetamido-4-hydroxyadamantane (170 mg, 40%)
