Abstract

Novel halogen derivatives of clavulanic acid are described which are of value in the preparation of a range of clavulins which either inhibit .beta.-lactamases or show activity against strains of both gram-positive and gram-negative bacteria. Processes for preparing the halogen derivatives are described and methods for converting them into the active clavulins are given.
