실험 절차

To a solution of (2S,4S)-4-dicyclohexylphosphino-2-diphenylphosphinomethylpyrrolidine [IV′] (46 mg, 0.1 mmol) dissolved in 1 ml of methylene chloride was added a solution of di-tert-butylcarbonate (24 mg, 0.11 mmol) dissolved in 11 mg (0.11 mmol) of triethylamine and 2 ml of methylene chloride and the resultant mixture was stirred for 2 to 3 hours at room temperature under nitrogen atmosphere. The reaction solution was concentrated under vacuum to afford white crystalline BCPM (50 mg, 86%), mp. 171 to 174° C.
