実験手順

N-Benzyloxycarbonyl-L-leucyl-L-phenylalanine diazomethylketone (314 mg) was dissolved in furfuryl alcohol (2 ml) and methylene chloride (1 ml). To the solution was added rhodium acetate (II) dimer (10 mg). After the mixture was stirred at room temperature for 1 hour, the solvents was removed in vacuo and the residue was chromatographed on a silica gel column, eluting with hexane-ethyl acetate to give the titled product (27 mg).
