The stereospecific synthesis of the functionalized carbapenam core 16 from the serine-derived trisubstituted pyrrolidine 9 is reported. The synthetic strategy relies on synthesizing an appropriately functionalized pyrrolidine, followed by an intramolecular azetidone formation utilizing a modified Mukiyama reagent. The efficient one-pot conversion of the benzenesulfonamide-protected pyrrolidine 9 to the Cbz-protected pyrrolidine 10 is also reported.
