Herein, we report the development of mild, organocatalyzed routes to novel carbapenam derivatives through aldol, Mannich and Michael C–C bond forming reactions.

An efficient diastereoselective synthesis of carbapenem Mannichbases was developed using organocatalysis. This method also provides a route to new highly functionalized diazabicyclo[4.2.1]nonanes of proposed biological significance.
