Abstract

The oxofuryl ester derivatives of 6-(.alpha.-amino-phenylacetamido)penicillanic acid, 7-(.alpha.-aminophenylacetamido)-cephalosporanic acid, or 7-(.alpha. -aminophenylacetamide)desacetoxycephalosporanic acid represented by the general formula ##SPC1## Wherein A represents ##SPC2## Wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom or a lower alkyl group, said R.sup.1 and R.sup.2 may form together a 1,3-butadienylene group, R.sup.3 represents a hydrogen atom or an acetoxy group, and Means a single bond or a double bond, and acid addition salts of them.
