Among commercially available antibiotics, β-lactam ring-containing β
- Lactam antibiotics, ie penicillins and cephalosporins, are the best known and most frequently used. Although these β-lactam antibiotics are widely used as useful chemotherapeutic agents, they are not sufficiently effective against certain microorganisms due to their resistance. The resistance of some of these microorganisms to β-lactam antibiotics is
It is usually caused by β-lactamases produced by the microorganisms, that is, enzymes that cleave the β-lactam ring of β-lactam antibiotics to produce products without antibacterial activity. Therefore, in order for the β-lactam antibiotics to exhibit sufficient efficacy, β-lactam antibiotics must be
It is necessary to eliminate or minimize the action of lactamases. This elimination or inhibition of the action of β-lactamase is achieved by a β-lactamase inhibitor, and such a β-lactamase inhibitor can be used together with a β-lactam antibiotic to improve the antibacterial effects of the antibiotic. Activity can be increased.

-Dioxide iodomethyl ester (1.27 g) was added, and the mixture was stirred at the same temperature for 2 hours. Next, 13 ml of ethyl acetate was added and the mixture was washed twice with 6 ml of ice water. The washing solution was re-extracted with ethyl acetate and combined with the previous ethyl acetate solution, 10 ml of ice water was added thereto, and the pH was adjusted to 3.0 with 6N aqueous hydrochloric acid. The aqueous layer was separated, and the organic layer was re-extracted with 2.5 ml of water. Combined with the previous water layer,
The mixture was saturated with sodium chloride and extracted with dichloromethane. After drying the dichloromethane solution over magnesium sulfate, the solvent was distilled off under reduced pressure. Dissolve the residue by adding water and freeze-dry it to a melting point of 155-170.
0.9 g of amorphous crystals (yield: 48%) were obtained.
