    摘要: Antibacterial 1-oxadethiacephalosporins of the formula: ##STR1## wherein Ar is ##STR2## (in which Acyl is organic or inorganic acyl); COB.sup.1 and COB.sup.2 each is carboxy or protected carboxy;Het is ##STR3## (in which COB.sup.3 is carboxy or protected carboxy); and Y is hydrogen or methoxy;and when COB.sup.1 and COB.sup.2, and/or COB.sup.3 is carboxy, pharmaceutically acceptable salts thereof are included, but with a proviso that when Y is methoxy, Het is ##STR4## a pharmaceutical or veterinary composition comprising the said 1-oxadethiacephalosporins and pharmaceutical carrier, and a method for treating or preventing human or veterinary infectious diseases comprising administering the said 1-oxadethiacephalosporin.Also disclosed are epimers of the compounds of formula (I) wherein the asymmetric carbon of the malonic methine is in the D(R)- or L(S)- configuration. The individual epimers are separable by column chromatography and/or crystallization. The bactericidal activity of the D-epimers is greater than that of the L-epimers or the mixtures of the epimers.
