Functionalized beta-lactams are synthesized by carbonylative ring expansion of silylated hydroxymethyl aziridines catalyzed by dicobalt octacarbonyl, a process that proceeds with inversion of configuration. Ring opening and elimination occurs on attempted carbonylation of aziridine carboxylates.

Abstract
Functionalized beta-lactams are synthesized by carbonylative ring expansion of silylated hydroxymethyl aziridines catalyzed by dicobalt octacarbonyl, a process that proceeds with inversion of configuration. Ring opening and elimination occurs on attempted carbonylation of aziridine carboxylates.
