Popis: | A series of benzo-fused tricyclic β-lactams, most of them phosphonobenzocarbacephems, were prepared in a straightforward way starting from phosphonoazadienes. In this paper, the synthetic route including a Staudinger reaction towards the β-lactams, followed by radical ring closing with tributyltin hydride and AIBN, which resulted in the envisaged tricyclic compounds, is reported. |
