実験手順
A mixture of (+)-camphanic chloride (19 mg, 00868 mmol), aminoglutarimide (21 mg, 0.0868 mmol) and Et3N (24 μl) in CHCl3 (1 ml) was stirred at room temperature for 16 hours. The solution was diluted with CHCl3, washed with saturated aqueous solution of NaHCO3, dried over Na2SO4, concentrated and purified by chromatography (silica gel, CH2Cl2; EtOAc=10:1) to give product (16 mg, 60.0% yield) as a colorless gel: 13CNMR (CDCl3) δ 172.6, 169.4, 168.6, 165.5, 90.3, 58.3, 53.3, 48.2, 47.6, 29.2, 28.2, 26.9, 22.7, 14.6, 7.6; MS (CI/CH4) m/z 308 (M+). This compound exhibited angiogenic activity in the assay of Example 13.
