(9H、s) DETAILED DESCRIPTION OF THE INVENTION The present invention relates to novel β-lactam compounds. More specifically, the present invention relates to the general formula () [However, Y represents an amino group, a phthalimide group, or a phenyl acetamide group, X represents a methoxy group, an azido group, a substituted or unsubstituted tetrazolylthio group, and R represents a hydrogen atom or a tert-butyl group]
When the β-lactam compound represented by and Y is an amino group, it relates to an acid addition salt thereof. Many β-lactam antibiotics are being developed to provide superior chemotherapeutic agents for the treatment of various bacterial infections. The present inventors have made great efforts to search for better and more useful compounds, and have synthesized compounds having various carbacefem skeletons as described in the present invention. These compounds, as exemplified in the reference examples, acylate the amino group at the 7-position with various acyl groups to produce β-lactam compounds that have strong antibacterial activity against a wide range of Durham-positive bacteria and Gram-negative bacteria. It is a useful intermediate that can be derived from The present invention will be explained in more detail below. The present invention provides a β-lactam compound represented by the general formula (). Examples of substituents for the tetrazolylthio group in X of the compound represented by the general formula () include lower alkyl groups having 1 to 5 carbon atoms. The β-lactam compound represented by the general formula () can be produced by the following method. The raw material compound () can be produced by the method described in Reference Examples. In the step ()→(a), treatment is performed with a halogenating agent used in the halogenation reaction at the allylic position, such as N-halosuccinimide such as N-bromosuccinimide, N-haloacetamide bromine, and pyrrolidone hydrotribromide. The solvent used is preferably a halogenated hydrocarbon such as dichloromethane, chloroform, carbon tetrachloride, etc., and the reaction is carried out at room temperature to the reflux temperature of the solvent used. Note that better results can be obtained if a catalyst such as perbenzoic acid or azobisiributyronitrile is used during the reaction. Various nucleophilic reagents are added to the halogen derivative thus obtained to obtain a substituent represented by X. As nucleophilic reagents, heterocyclic thiols, pyridines, sodium azide, methanol can be used directly, or hydrogen bromide, hydrogen chloride, protonic acids such as P-toluenesulfonic acid, zinc chloride, aluminum chloride, tin chloride, tetrachloride, etc. React in the presence of a Lewis acid such as titanium chloride, or with a heterocyclic thiol, if necessary, in the presence of an organic amine such as potassium carbonate, sodium hydrogen carbonate, silver carbonate, silver oxide, triethylamine, pyridine, or a base such as sodium hydride. Do this. Examples of solvents include aprotic halogenated solvents such as methylene chloride, chloroform, and carbon tetrachloride, ether solvents such as tetrahydrofuran and dioxane, ester solvents such as ethyl acetate, dimethylformamide, dimethyl sulfoxide, and hexamethylphosphoramide. Aprotic polar solvents such as acetone, acetonitrile, etc. are used alone or in combination. The reaction temperature is -20°C to 100°C. In addition, in the stereochemistry of the group
It is possible to selectively synthesize more of one of the two or almost only one of the two. (a) → (b) and (f) → (c)

Examples include hydrogen chloride. Solvent: ethyl acetate,
Methylene chloride, anisole, etc. can be used alone or in combination, and this reaction can be carried out without a solvent. The reaction is carried out between -10° and 60°C. The phenylacetylation reaction step (c)→(d) can be carried out by an acylation reaction using a conventional acid chloride method using phenylacetyl chloride. The reaction is carried out between -10° and 35° C. using aqueous tetrahydrofuran, aqueous acetone, aqueous dioxane, etc. as a solvent and sodium bicarbonate, potassium carbonate, triethylamine, etc. as a base. The optical selective deacylation reaction step (d) → (e) with acylase includes a microorganism that optically deacylates a compound () to produce an optically active compound (), and a cultured product of the microorganism. ,
And/or it can be carried out using an enzyme produced by the microorganism. This method can be carried out, for example, by the method disclosed in JP-A-56-61377, 56-61378, and the like. The details of the present invention will be illustrated below by way of Examples.

was dissolved in a mixed solvent of 400 ml of methylene chloride and 20 ml of acetone, and 7.1 g of p-toluenesulfonic acid monohydrate was added to the solution under ice-cooling and stirring, and the stirring was continued for 1 hour and 30 minutes. Water was added to the reaction solution, the organic layer was washed with water, and then diluted with saturated brine.
Wash once with saturated deuterated water and then three times with saturated saline. After drying the organic layer over anhydrous sodium sulfate, the solvent was distilled off to obtain 35 g of an oil (hereinafter abbreviated as crude aldehyde compound).
When this crude aldehyde compound was purified by silica gel chromatography (Wako Gel C-200, 600 ml, elution: n-hexane: ethyl acetate 1:1 v/v), the desired product was obtained as a diastereomer mixture.
28.3 g (72.7% yield) are obtained as a crystalline oil. The physical properties of this material are as follows. IRνcm−1 max (CHCl 3 ): 1790 (sh), 1780, 1730,

Production of azabicyclo[4,2,0]oct-2-ene-8-oxo-2-carboxylic acid, tert-butyl ester: Cis-4-(3-oxo-1-propene obtained in 7-2) -1-yl)-3-phthalimido-2-oxoazetidin-1-yl-α-diethylphosphonoacetic acid, tert-butyl ester (60 g) was dissolved in dimethoxyethane (600 ml), 5% palladium on carbon (30 g) was added, and the mixture was heated at 40°C under stirring. Pass hydrogen gas for an hour. After the reaction, the catalyst was separated, and then 20 g of diazabicyclooctane was added to the reaction mixture, and the mixture was left at room temperature overnight. Add 1 of chloroform to this reaction solution, wash with dilute hydrochloric acid and water, concentrate under reduced pressure, and treat the residue with ethyl acetate to obtain colorless needle-like crystals. 29.6g (70%)
