実験手順
To a solution of benzyl (1S,2R,3S,5S)-2-(1,3-dioxoisoindolin-2-yl)bicyclo[3.1.0]hexan-3-ylcarbamate (4.0 g, 10.638 mmol) in chloroform (30 mL) at room temperature was added trimethylsilyl iodide (14.6 mL, 106.380 mmol) dropwise, and the resulting mixture was stirred at room temperature for 1 hour. The reaction was quenched with methanol (5 mL), diluted with ethyl acetate (150 mL), and washed with water (3×50 mL) and brine (50 mL). The organic layer was dried over sodium sulfate, filtered and concentrated to afford a crude compound, which was directly used in the next reaction without further purification. MS (ES+) C14H14N2O2 requires: 242, found: 243 [M+H]+.
