実験手順

(2R,4R)-4-methoxy-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester (0.350 g, 1.427 mmol), aniline 1 (0.273 g, 1.427 mmol) and EEDQ (0.529 g, 2.140 mmol) were dissolved in CHCl3 (30 mL). Et3N (0.6 mL, 4.281 mmol) was added and the reaction mixture was heated at reflux for 18 h. The mixture was allowed to cool and diluted with CHCl3 (100 mL) and washed with 5% HCl, 0.5 N NaOH, water and brine (40 mL each), the organic extract was dried over MgSO4, filtered and the solvent removed to give a pale tan foam. The crude product was used for the next step without purification. MS: APCI (AP+): 419.2 (M)+, (AP−): 417.2 (M)−.
