A compound having the formula (I): ##STR1## is described, together with salts thereof and an enzymatic process for converting such compounds into clavulanic acid. A process for the preparation of the compound of formula (I) and its salts is disclosed, together with intermediates for use therein. This process involves the use of a novel enzyme system to effect the desired cyclisation, which enzyme system is preferably derived from a micro-organism, in particular a species of Streptomyces.
