Synthesis and antibacterial activity of 3-acylamino-2-azetidinone-1-sulfonic acid derivatives

Sulfazecin is a monocyclic β-lactam antibiotic isolated from strain G-6302, Pseudomonas acidophila. As a key intermediate for the synthesis of sulfazecin derivatives, 3-amino-2-azetidinone was synthesized from penicillins, and various new compounds were s
