Useful antibacterial agents in which a penicillin and/or a beta-lactamase inhibitor are linked via 1,1-alkanediol dicarboxylates are of the formula
where A is the residue of certain dicarboxyic acids, R3 is H or (C1-C3)alkyl, n is zero or 1 such that when n is zero R is P or B and R1 'is the residue of certain esters, H or a salt thereof; and when n is 1, one of R and R1 is P and the other is B, and P is
where R2 is H or certain acyl groups, and B is the residue of a beta-lactamase inhibiting carboxylic acid; a method for their use, pharmaceutical compositions thereof and intermediates useful in their production.
