Abstract

The invention relates to penicillins of formula and non-toxic salts thereof, where R is phenyl, substituted phenyl or thienyl and X is a divalent radical derived from a cyclopropane, oyclobutane, cyclopentane, cyclohexane, cyclohexene or cyclohexadiene ring system or from a 5- or 6-membered saturated or unsaturated heterocyclic ring containing a single hetero atom which is O or S. The X rings may be substituted with one or more substituents, e.g. halogen, C 1-5 alkyl, oxo or carboxyl. The cyclohexane, cyclohexene and cyclohexadiene rings may be bridged by means of -O- -O-CO-, -CH 2 - or -CH=CH-. The compounds may be prepared by reacting an [alpha]-amino penicillin of formula with a reactive derivative of the dicarboxylic acid HOOC-X-COOH, wherein X and R have the above values. The reactive derivative may be a cyclic anhydride or a bis-acid chloride. Typical compounds are 6 [D - [alpha] - (cis - 2 - carboxy cyclohexane - 1 - carbamido) phenylacetamido] penicillanic acid, 6 - [D - [alpha] - (cis - 2 - carboxy cyolohex - 4 - ene - 1 - carbamido) phenylacetamido] penicillanic acid and 6 - [D - [alpha] - (1 - carboxy cyclobutane - 1 - carbamido) phenylacetamido] penicillanic acid. The salts may be sodium, potassium, calcium, ammonium, aluminium or amine salts. The dimeric anhydride of furan-3,4-dicarboxylic acid is prepared by treating furan-3,4- dicarboxylic acid with thionyl chloride in benzene.
