    • There are described compounds of the formula ##STR1## in which R signifies lower alkoxycarbonyl, lower alkoxycarbonylamino, the acyl residue of an .alpha.- or .beta.-amino acid or a residue of the general formulaQ--X--Y-- (a)wherein Q signifies a 3- to 6-membered ring which optionally contains nitrogen, sulphur and/or oxygen and which is optionally bonded with a fused ring, X signifies a direct bond or a linear "spacer" with up to 6 atoms consisting of carbon, nitrogen, oxygen and/or sulphur, of which up to 2 atoms can be nitrogen atoms and 1 atom can be oxygen or sulphur, and Y represents one of the groups --CO--, --CS--, --CONH-- and (where X contains neither sulphur nor carbonyl as a terminal component) --SO.sub.2 --;and in which R.sup.1 signifies hydrogen, halogen, carbamoyloxy, lower alkanoyloxy or a group of the formula --S--Het, wherein Het represents a 5- or 6-membered heteroaromatic group containing nitrogen, sulphur and/or oxygen, and R.sup.2 represents the sulpho group --SO.sub.3 H or R.sup.1 and R.sup.2 together signify a group of the formula ##STR2## wherein A represents hydrogen or a residue which is usable in the 3-position of cephalosporin antibiotics, and in which R.sup.3 represents hydrogen or R.sup.1 and R.sup.3 together represent a group of the formula.dbd.CH--R.sup.a (c)wherein R.sup.a signifies one of the groups--COR.sup.b (c.sup.1)--CH.sub.2 --OCOR.sup.c (c.sup.2)--CH.sub.2 --NR.sup.d R.sup.e (c.sup.3)--CH.sub.2 --S--Het (c.sup.4)in which R.sup.b represents lower alkoxy or amino, R.sup.c represents lower alkyl, phenyl or amino, R.sup.d and R.sup.e each independently represent hydrogen or lower alkyl or R.sup.d and R.sup.e together with the N atom to which they are attached represent a 5- or 6-membered N-heterocycle which optionally contains a further nitrogen, oxygen or sulphur atom and Het represents a 5- or 6-membered heteroaromatic group containing nitrogen, sulphur and/or oxygen,and pharmaceutically compatible salts of these compounds.The products have .beta.-lactamase inhibiting properties. They are useful in combination with .beta.-lactam antibiotics in the control of .beta.-lactamase forming pathogens.
