Spirocyclic Side-chain Derivatives of Penicillin and Cephalosporin

A series of two spirocyclic oxazolidinone derivatives of penicillin and four derivatives of cephalosporin have been prepared, as well as a benzoxazine conjugate of cephalosporin, with the object of freezing the conformation of the 6(7)-amide side-chain bearing a pendant aromatic ring.The antibacterial properties of these derivatives are discussed.
