    摘要: A compound of the formula:R--CH.dbd.N--SO.sub.3.sup..crclbar. Z.sup..sym. (II)[R is an organic residue derived by removal of one hydrogen atom attached to a carbon atom of an organic compound; Z.sup..sym. is a lipophilic quaternary ammonium group], and a method of producing a 2-azetidinone-1-sulfonic acid compound of the formula: ##STR1## [R and Z.sup..sym. have the same meanings as respectively defined above; R.sup.1 is an acylated or protected amino group or an azide group], being a useful intermediate for the production of antimicrobial agents having excellent antimicrobial and .beta.-lactamase-inhibitory activities, by reacting a compound (II) with a reactive derivative of a carboxylic acid of the formula:R.sup.1 --CH.sub.2 COOH[R.sup.1 is the same meaning as defined above] in the presence of a base.

    摘要: Novel 7-[2-(2-aminothiazol-4-yl)-2-(syn)-methoxyiminoacetamido]cephalosporanic acid derivatives of the formula: ##STR1## wherein R.sup.1 NH is an amino group which may optionally be protected, R.sup.2 is a halogen atom or a hydroxyl, thiol or amino group which may optionally be substituted; COOR is a carboxyl group which may optionally be esterified, and pharmaceutically acceptable salts thereof, have excellent antimicrobial activity against a broad spectrum of microorganisms including Gram-negative bacteria such as Escherichia coli, Serratia marcescens, Proteus rettgeri, Enterobacter cloacae, Citrobacter freundii. Thus, these compounds may be used as antibacterial agents for therapeutic purposes.
