A New Synthetic Method of 3-Formylcephalosporins

A New Synthetic Method of 3-Formylcephalosporins

Cephalosporin 3'-bromolactones (3) were prepared in good yields via silyl ethers (2) starting from readily available cephalosporin lactones (1). Treatment of 3 with dimethyl sulfoxide yielded 3-formylcephalosporins (4), a useful intermediate for the chemical modification at the C3-position of c...
