The present invention provides a process for inversion of the absolute stereochemistry at the .alpha.-carbon atom of a C-6 substituent of a bicyclic carbapenem antibiotic via a phosphorus - azodicarboxylate mediated reaction. Novel azides, amines and formates are described as useful intermediates and as antibacterial agents.
