    Abstract: Useful antibacterial agents in which a penicillin and/or a beta-lactamase inhibitor are linked via 1,1-alkanediol dicarboxylates are of the formula ##STR1## where A is the residue of certain dicarboxyic acids, R.sup.3 is H or (C.sub.1 -C.sub.3), n is zero or 1 such that when n is zero R is P or B and R.sup.1 is the residue of certain esters, H or a salt thereof; and when n is 1, one of R and R.sup.1 is P and the other is B, and P is ##STR2## where R.sup.2 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.

    Abstract: 6-Alkoxylated-6-acylamidopenicillanic acids and 7-alkoxylated-7-acylamidocephalosporin acids and esters thereof, are provided by reacting a 6-acylamidopenicillanic acid ester or a 7-acylamidocephalosporin ester under anhydrous conditions at -90.degree. C. to -15.degree. C. with an alkali metal salt of a lower alkyl alcohol in the presence of an excess of the corresponding alcohol to produce, in situ, the anionic form of the antibiotic which on halogenation with a positive halogen compound, e.g. t-butyl hypochlorite, yields the compound of the invention. Compounds of the invention, e.g. 6-methoxy-6-phenoxyacetamidopenicillanic acid and 7-methoxy-7-[2-(2-thienyl)acetamido]cephalosporanic acid are useful antibiotics.
