- The β-lactams retain a central place in the antibacterial armamentarium. In Gram-negative bacteria, β-lactamase enzymes that hydrolyze the amide bond of the four-membered β-lactam ring are the primary resistance mechanism, with multiple enzymes disseminating on mobile genetic elements across opportu …
- β-Lactams remain one of the most commonly involved medications in allergic drug reactions. The four main groups share in common a four-member β-lactam ring; and if this ring is fused to a thiazolidine ring, the β-lactam is classified as a penicillin. This includes piperacillin and the antistaphylococcal penicillins.
- A convenient Kinugasa reaction protocol enables a one-pot synthesis of 4-substituted β-lactams from inexpensive calcium carbide and nitrone derivatives. Calcium carbide is thereby activated by TBAF·3H 2 O in the presence of CuCl/NMI. The reaction provides rapid access to practical quantities of β-lactams substituted at position 4.
