摘要: A process is described for selectively obtaining 1-β-methylcarbapenem intermediates. The desired chirality is obtained through the hydrogenation of certain bicyclic β-lactam ring structures containing an exocyclic methylene double bond alpha to the β-lactam ring, in the presence of a Group VIII metal hydrogenation catalyst. The hydrogenation results in a mixture of a- and β-methyl epimers having a high β/α epimeric ratio. New 1-β-methyfcarbapenem intermediates made by the process are also described.
