摘要：
The present invention relates to hitherto unknown compounds of the general formula I: ##STR1## in which R.sub.1 stands for a phenyl, 4-hydroxyphenyl, 1,4-cyclohexadienyl or a 3-thienyl group; R.sub.2 represents a primary amino or a carboxy group; R.sub.3 is a hydrogen atom, or a lower alkyl, aryl or aralkyl radical, and A stands for a radical of a .beta.-lactamase inhibitor containing a .beta.-lactam ring as well as a carboxy group, A being connected via the carboxy group.The present invention provides new compounds useful in the treatment of bacterial infections. The new compounds are in particular strongly active against .beta.-lactamase producing bacteria.
