5-isothiazolidinonyl radical (6) to a β-lactam. However, generation of the model radicals (13 and 20) did not lead to β-lactams. The analogous reaction of a 5-isoxazolidinonyl radical is the basis for a potential synthesis of clavulanic acid, but again the rearrangement was not observed in the model radical (24).
青霉素生物合成的可能机制涉及将5-异噻唑烷酮基(6)重排为β-内酰胺。然而,模型自由基(13和20)的产生并未导致β-内酰胺。5-异恶唑烷二酮基团的类似反应是潜在合成棒酸的基础,但再次在模型基团中未观察到重排(24)。
