Some new b-lactams bearing biologically important morpholine ring have been synthesized by acylation of amino b-lactams in the presence of morpholine-4-carbonyl chloride. These novel β-lactams were prepared under mild reaction conditions without any solvent in short reaction times. Their biological activities have been examined against microbial agents such as Staphylococcus aureus (S. aureus),...

The four-membered cyclic amides commonly known as 2-azetidinones or β-lactams occupy a prominent place in the realm of organic and medicinal chemistry since the structure elucidation of penicillin showed the presence of β-lactam ring in it and the antibacterial activity of penicillin was attributed to the presence of β-lactam ring. The early investigations in organic chemistry were focused on d...
