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

As a key intermediate for the synthesis of sulfazecin derivatives, 3-amino-3-methoxy-2-azetidinone (24 or 26) was synthesized from penicillins, and various new compounds, including sulfazecin, were synthesized by acylation and sulfonation of 24 or 26. Som

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
