Ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl,
such as pentyl, hexyl, heptyl, octyl, dodecyl or lauryl; alkoxy refers to -O-alkyl having an alkyl group as defined above; lower alkyl refers to C 1-5 alkyl, such as methyl, ethyl, n -propyl, isopropyl, n-butyl, isobutyl, sec-butyl,
tert-butyl or pentyl; lower alkoxy refers to -O-lower alkyl having a lower alkyl group as defined above; acyl refers to C1-12 acyl, such as acetyl, propionyl, butyryl, benzoyl, naphthoyl , pentanecarbonyl, cyclohexanecarbonyl, furoyl or thenoyl; acyloxy refers to -O-acyl having an acyl group as defined above; alkylthio refers to -s- having an alkyl group as defined above;
Alkyl; alkenyl is C 2-10 alkenyl,
For example, vinyl, allyl, iso-propenyl,
2-pentenyl or butenyl, etc.; alkynyl refers to C 2-10 alkynyl, such as ethynyl or 2-propynyl; cycloalkyl refers to C 3-7 cycloalkyl, such as cyclopropylcyclobutyl, cyclopentyl, cyclohexyl or cycloheptyl; cycloalkenyl refers to C 5-7 cycloalkenyl, such as cyclopentenyl, cyclohexenyl, cycloheptenyl, etc.; aryl refers to, for example, phenyl, naphthyl or indanyl; aryloxy refers to Having an aryl group defined in â
O-aryl; aralkyl is, for example,
benzyl, phenethyl, 4-methylbenzyl or naphthylmethyl; aralkyloxy means -o- having an aralkyl group as defined above;
Aralkyl group; heterocyclic group refers to a heterocyclic group containing at least one heteroatom selected from oxygen, nitrogen and sulfur, such as furyl, thienyl, pyrrolyl, pyrazolyl, imidazolyl, thiazolyl, isothiazolyl, Oxazolyl, isoxazolyl, thiadiazolyl, oxadiazolyl, thiatriazolyl, oxatriazolyl, triazolyl, tetrazolyl, pyridyl, 4-(5

quinolyl, phenazinyl, 1,3-benzodioxolanyl, benzofuryl, benzothienyl, benzoxazolyl, benzothiazolyl or coumarinyl; heterocyclic alkyl refers to a group consisting of a heterocyclic group and an alkyl group as defined above; ; The halogen atom means, for example, fluorine, chlorine, bromine or iodine atom, respectively. R 1 in each general formula herein is a hydrogen atom or a carboxyl protecting group, and examples of the carboxyl protecting group include those conventionally used in the field of penicillin and cephalosporin compounds. These carboxyl-protecting groups include ester-forming groups that are eliminated by treatment under catalytic reduction, chemical reduction, or other mild conditions, or ester-forming groups that are easily eliminated in vivo, or treated with water or alcohol. Examples thereof include an organic silyl group, an organic phosphorus group, an organic tin group, etc., which are easily eliminated in this case, and various other known ester-forming groups. Among these types of protecting groups, suitable protecting groups include:
Specifically, the following can be mentioned. (a) Alkyl group. (b) At least one of the substituents is halogen, nitro, acyl, alkoxy, oxo, cyano, cycloalkyl, aryl, alkylthio, alkylsulfinyl, alkylsulfonyl, alkoxycarbonyl, 5-alkyl-2-oxo-1,3 -dioxol-4-yl, 1-indanyl, 2-indanyl, furyl, pyridyl,

4.55ïŒ2Hãbsã [ Formula ] Silyl derivatives , phosphorus derivatives , or All compounds frequently used in acylation reactions, such as tin derivatives, are included. General formula [], [], [], [] or [
] Specifically, the reactive derivatives at the carboxyl group of the compound include acid halides, acid anhydrides, mixed acid anhydrides, activated acid amides,
Active ester and general formula [], [],
Examples include reactive derivatives of the compound of [], [] or [] and the Vilsmeier reagent. Examples of mixed acid anhydrides include mixed acid anhydrides with carbonic acid monoalkyl esters such as carbonic acid monoethyl ester and carbonic acid monoisobutyl ester, and lower alkanoic acids which may be substituted with halogen such as pivalic acid and trichloroacetic acid. Mixed acid anhydrides and the like are used. Examples of active acid amides include N-acyl saccharin, N-acylimidazole, N-acylbenzoylamide, N,N'-dicyclohexyl-
N-acylurea, N-acylsulfonamide, etc. are used. Next, as the active ester, for example, cyanomethyl ester, substituted phenyl ester, substituted benzyl ester, substituted thienyl ester, etc. are used. In addition, examples of derivatives reactive with the Vilsmeier reagent include N,N-dimethylformamide,
Acid amides such as N,N-dimethylacetamide are treated with halogenating agents such as phosgene, thionyl chloride, phosphorus trichloride, phosphorus tribromide, phosphorus oxychloride, phosphorus pentachloride, trichloromethyl chloroformate, and oxalyl chloride. Examples include derivatives reactive with Vilsmeier's reagent obtained by General formula [], [], [], [] or [
] When using each compound in the form of a free acid or salt, a suitable condensing agent is used. Such condensing agents include, for example, N,N'-dicyclohexylcarbodiimide,
N'-disubstituted carbodiimides; azolide compounds such as N,N'-thionyldiimidazole;
N-ethoxycarbonyl-2-ethoxy-1,
Dehydrating agents such as 2-dihydroxyquinoline, phosphorus oxychloride, and alkoxyacetylene; 2-halogenopyridinium salts such as 2-chloropyridinium methyl iodide and 2-fluoropyridinium methyl iodide are used. This acylation reaction is generally carried out in a suitable solvent.
It is carried out in the presence or absence of a base. Examples of solvents include halogenated hydrocarbons such as chloroform and methylene chloride; ethers such as tetrahydrofuran and dioxane; N,
N-dimethylformamide, N,N'-dimethylacetamide, acetone, water or a mixture thereof can be used. In addition, as a base, an inorganic base such as alkali hydroxide, alkali hydrogen carbonate, alkali carbonate or alkali acetate;
Examples include organic bases such as tertiary amines such as trimethylamine, triethylamine, tributylamine, pyridine, N-methylpiperidine, N-methylmorpholine, lutidine, and collidine, and secondary amines such as dicyclohexylamine and diethylamine. In addition, general formula [a] or [
The compound of the general formula [] or its salts which can be derived from the compound of b] or its salts can also be produced as follows. In order to obtain the compound of the general formula [] or its salts using the compound of the general formula [] or its salts, the reaction of diketene with a halogen such as chlorine or bromine [Journal of the Chemical Society, 97] , 1987 (1910)] and a compound of the general formula [] or a salt thereof may be reacted according to a conventional method. Conditions and operations known in the art can be applied to this reaction condition and operation. Also, general formula []
The salts of the compound of formula [] can be easily obtained according to conventional methods, and the salts include the same basic or acidic group salts as explained above for the salts of the compound of the general formula []. It will be done. The resulting compound of general formula [] or its salts may be isolated and purified by conventional methods, but may also be used in the next reaction without isolation. The amount of the compound of the general formula [], [], [], [], or [] or its reactive derivative at the carboxyl group or their salts is the same as the amount of the compound of the general formula [] or its reactive derivative at the amino group. Or each is preferably about 1 to several mol each per 1 mol of the salt. These reactions are usually carried out at -50 to 40°C,
Completes in 10 minutes to 48 hours.
