This novel substrate can be directly alkylated on the nitrogen atom of the β-lactam ring in contrast to commercially available 4-acyloxyazetidin-2-one. Moreover, subsequent cyclization via intramolecular

While the C2–C3 bond formation has scarcely been explored, the intramolecular cyclization through the C3–C4 bond using different approaches are among the
