<p>It is an object of the invention to find a less expensive and highly safe synthetic route for carbapenem-type antibacterial agents suitable for large-scale synthesis. A production process for the preparation of carbapenem-type antibacterial agents:
(R 1 is a C 1 -C 3 alkyl group, n is 0, 1 or 2, A is a C 1 -C 3 alkylene group, L is a leaving group, R 3 is a hydrogen atom, a C 1 -C 3 alkyl group or an amino protecting group, and the hydroxyl or carboxyl groups can independently be protected) using an amine compound (1) or a salt thereof as a synthetic intermediate is provided.</p> |
