実験手順

To a solution of 4-(4-oxo-pent-2-enyl)-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester (193 mg, 0.5 mmol, 1 equiv) in benzene (0.9 mL) was added a solution of triphenylphosphine-copper (I) hydride hexamer in benzene (3.6 mL). The mixture was stirred at rt overnight and hexane (13 mL) was added. The mixture was filtered and the filtrate was evaporated. The residue was purified by chromatography to give 4-(4-oxo-pentyl)-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester (127 mg, 65%).
