Abstract

A two-stage flow process for cGMP manufacture of a commercially important carbapenem intermediate was developed. Stage 1 featured an intramolecular N–H insertion reaction catalyzed by an immobilized rhodium catalyst. In stage 2, phosphorylation of the resulting keto ester intermediate afforded the target, which was isolated in batch mode. The equipment design and process control strategy leading to validation of the process at the 100 kg scale are discussed.
