A benzo-fused oxapenem from a β-lactam-4-ylidene

Spiro-fused β-lactam oxadiazoline 2a was prepared from acetone semicarbazone in five steps. Thermolysis of 2a at 100°C in benzene led to carbene 3a, which cyclized to the benzo-fused oxapenem derivative 4 via intramolecular OH insertion. Compound 10, with
