Abstract
For a series of active phosphonate esters, the anhydride abbreviated as ANPTA (6a) exhibits the highest reactivity in the preparation of ceftriaxone. The synthesis of ceftriaxone was optimized with the pilot-scale yield reaching 95.7%. The results were explained from the structural viewpoint and supported by analysis of the calculated Mulliken atomic charge distribution.
