以螺[吲哚啉-3,4'-哌啶]-2-酮 (2.73 g, 11.42 mmol) 和二碳酸二叔丁酯 (2.74 g, 12.57 mmol) 为原料,在室温下,将螺[吲哚啉-3,4'-哌啶]-2-酮溶于四氢呋喃 (100 mL) 中,依次加入二碳酸二叔丁酯和三乙胺 (2.38 mL, 17.135 mmol)。反应混合物在室温下搅拌4小时。反应完成后,减压蒸发除去溶剂,残余物用水和二氯甲烷的混合物处理。水层用二氯甲烷萃取三次,合并有机层,用无水硫酸钠干燥,过滤后浓缩,得到2-氧代螺[二氢吲哚-3,4'-哌啶]-1'-羧酸叔丁酯 (4.02 g, 定量产率) 为白色泡沫。产物经1H NMR (400 MHz, DMSO-d6) 确认:δ 1.44 (s, 9H), 1.56-1.73 (m, 4H), 3.55-3.79 (m, 4H), 6.86 (dd, J = 7.70, 0.40 Hz, 1H), 6.95 (td, J = 7.59, 1.10 Hz, 1H), 7.19 (td, J = 7.70, 1.10 Hz, 1H), 7.43 (dd, J = 6.80, 0.70 Hz, 1H), 10.41 (br.s., 1H); m/z = 303.05 (M + H)。
