반응 단계
Pratt, U.S. Pat. No. 4,180,506, describes catalytic hydrogenation of 6,6-dibromopenicillanic acid over Pd/C catalyst to produce a mixture of 6-alpha- and 6-beta-bromopenicillanic acid. Clayton, J. Chem. Soc. (C), pp. 2123-2127 (1969), describes the hydrogenation of methyl 6,6-dibromopenicillanate over Pd/CaCO3 to produce methyl 6-alpha-bromopenicillanate and methyl penicillanate; and hydrogenation of 6,6-dibromopenicillanic acid over the same catalyst to produce penicillanic acid.
