| abstract |
Azetidine derivatives of the formula VII <IMAGE> in which the substituents have the meaning mentioned in Patent Claim 1 can be used as intermediates for the preparation of antimicrobially active 1-oxadethiocephalosporins. They are obtainable by ketalisation and if desired subsequent halogenation from compounds of the formula I. <IMAGE> |
