摘要:
A 1,1-dioxopenicillanic acid ester represented by formula (I) ##STR1## wherein R represents a methyl or phenyl group. The ester of formula (I) may be prepared by reacting 1,1-dioxopenicillanic acid or its salt with a compound represented by formula (III) ##STR2## wherein R is as defined above, and X represents a halogen atom, or by oxidizing a compound of formula (V) ##STR3## wherein R is as defined above. The ester of the formula (I) is useful as a .beta.-lactamase inhibitor and may be used in association with a .beta.-lactam antibiotic.
