Thus, the free acid (III), the alkali or alkaline earth metal salt (sodium, potassium or calcium salt) of this free acid (III), the organic amine salt (trimethylamine salt or pyridine salt) of the free acid (III), or its reactivity Derivative acid halides (acid chlorides or acid anhydrides), acid anhydrides, mixed acid anhydrides, active amides, active esters and the like are subjected to the acylation reaction described above.

Following the acylation reaction, the amino protecting group is removed as necessary. Removal of the amino protecting group can be carried out according to a method known per se such as Japanese Patent Application Laid-Open No. 1975-52083 and Pure Applied Chemistry 7,335 (1963) or a similar method. In compound (I), R 2 is monohalogenoacetyl (monochloroacetyl), and R 3 is amino-protected N-monohalogenoacetylcarbamoyloxy (N-monochloroacetylcarbamoyloxy) and In the case of the same carbamoyloxy group, these two monohalogenoacetyl groups (monochloroacetyl) can be removed at the same time. In this sense, the amino protecting group represented by R 2 is preferably a monohalogenoacetyl group. The reaction for removing a monohalogenoacetyl group from an amino group is carried out by reacting a compound of general formula (I) in which an amino group or amino groups are protected with monohalogenoacetyl with thiourea and a basic substance. Typically this reaction is carried out in a solvent at a temperature near room temperature, which is usually terminated within 1 to 10 hours. The solvent is sufficient as long as it does not interfere with the present reaction. Therefore, such solvents include ethers such as ethyl ether, tetrahydrofuran and dioxane, lower alcohols such as methanol and ethanol, halogenated hydrocarbons such as chloroform and methylene dichloride, esters such as ethyl acetate and butyl acetate, and acetone Ketones, such as methyl ethyl ketone, water, and mixtures of these solvents are mentioned.

상기 식에서, X 는 염소 또는 취소 등의 할로겐 원자, R6는 수소 또는 메틸기, R7은 메틸, 에틸 또는 프로필 등의 탄소 원자수 1 내지 3개인 저급 알킬기이다.Wherein X is a halogen atom such as chlorine or cancellation, R 6 is hydrogen or a methyl group, R 7 is a lower alkyl group having 1 to 3 carbon atoms such as methyl, ethyl or propyl.

상기 두 화합물의 경우에, R6이 각각 수소 또는 메틸기인 경우, 화합물(Ⅴ)은 통상 syn-및 anti-이성체의 혼합물로 얻어진다. 이 반응은 일반적으로 일반식(Ⅳ)의 화합물을 실온 또는 상온(上溫) (0°내지 100℃, 바람직하게는 10 내지 50℃)에서 에타놀, 메타놀 또는 테트라히드로푸란과 같은 유기 용매 중에서 티오우레아와 반응시킴으로써 수행된다. 반응시간은 1 내지 30시간, 바람직하게는 1 내지 5시간의 범위 내에서 선택된다. 화합물(Ⅷ)의 syn- 및 anti- 이성체의 혼합물로부터 소기의 syn- 이성체를 분리하기 위하여는 다음 방법 중의 한가지 방법을 성공리에 수행할 수 있다. 따라서, 이들 방법은 화합물(Ⅴ)의 할로겐화 수소염(HBr 또는 HCI 염) 또는 2-아미노기에 보호기가 있는 화합물(Ⅴ)의 유도체와 같은 화합물(Ⅴ)의 이성체의 결정화도 또는 용해도 차이를 이용하여 분별 결정화하여 크로마토그라피법으로 분리하는 방법과, 화합물(Ⅴ) 또는 2-아미노기에 보호기가 있는 화합물(Ⅴ)을 공지된 방법에 따라 그의 에스테르 위치에서 가수분해하여 일반식(Ⅲ)의 카르복실산 유도체를 생성시킬 때, anti- 이성체와 syn- 이성체간의 가수분해도의 차이를 이용하여 syn- 이성체만을 선택적으로 분리시키는 방법이 포함한다.In the case of the two compounds, when R 6 is each hydrogen or a methyl group, compound (V) is usually obtained as a mixture of syn- and anti-isomers. This reaction is generally carried out with the thiourea in an organic solvent such as ethanol, methanol or tetrahydrofuran at room temperature or room temperature (0 ° to 100 ° C., preferably 10 to 50 ° C.). It is carried out by reacting with. The reaction time is selected in the range of 1 to 30 hours, preferably 1 to 5 hours. To isolate the desired syn-isomer from the mixture of syn- and anti-isomers of compound (v), one of the following methods can be carried out successfully. Therefore, these methods fractionate using the crystallinity or solubility difference of the isomers of compound (V), such as the hydrogen halide salt (HBr or HCI salt) of compound (V) or a derivative of compound (V) having a protecting group on a 2-amino group. Crystallization to separate by chromatographic method, and compound (V) having a protecting group with compound (V) or 2-amino group by hydrolysis at the ester position thereof according to a known method to carboxylic acid derivative of general formula (III) In the process of producing the method, a method of selectively separating only syn-isomers by using the difference in degree of hydrolysis between anti- and syn-isomers is included.

최종 단계의 방법에서는, anti-이성체의 가수분해도가 syn- 이성체의 가수분해도보다 높기 때문에, 이성체가 선택적으로 가수분해되어 제거된다. 2-아미노기가 있거나 없는 화합물(Ⅴ)의 에스테르 결합을 가수분해시키기 위한 반응은 통상 수산화칼륨이나 수산화나트륨 등의 알칼리 금속 수산화물 1몰 당량 내지 수몰 당량의 존재하에 0℃ 내지 실온의 온도 범위내에서, 그리고 물 또는 메타놀, 에타놀, 아세톤, 테트라히드로푸란, 디옥산, N, N-디메틸포름아미드 또는 N, N-디메틸아세타미드 등의 수혼화성 유기용매와 물의 혼합물 중에서 수행할 수 있다. 화합물(Ⅴ)에서 R6이 수소일 경우, 분리된 syn- 이성체는 이 화합물(Ⅴ)을 메틸화시킴으로써 R6이 메틸인 화합물(Ⅴ)의 syn- 이성체로 전화시킬 수 있다. 이 메틸화 반응은 빙냉하 또는 실온 근처의 온도하에 용매 중에서 수행되는데, 대개의 경우 반응 종결시간은 수분내지 수시간이 소요된다. 이 목적에 사용되는 용매의 종류로는 반응을 저해하지 않는 여하한 용매라도 좋다. 그러므로, 예를 들면 테트라히드로푸란, 디옥산, 메타놀, 에타놀, 클로로포름, 염화메틸렌, 초산에틸, 초산부틸, N, N- 디메틸포름아미드, N, N-디메틸아세타미드, 물 및 이들 용제의 혼합물을 예거할 수 있다. 메틸화제로서는 옥화메틸, 취화메틸 등의 할로겐화메틸, 황산디메틸 및 디아조메탄 등을 열거할 수 있다. 디아조메탄을 사용하는 경우를 제외한 모든 경우에, 이 수소인 화합물(Ⅴ)은 알킬리 금속 탄산염(탄산나트륨, 탄산칼륨 등) 또는 알칼리 금속 수산화물(수산화나트륨, 수산화 칼륨 등)과 같은 염기 존재하에 상기 메틸화제와 반응한다. 화합물(Ⅲ) 및 이와 같이하여 얻은 화합물(Ⅴ)의 syn- 이성체의 물리정수는 대응하는 anti-이성체의 물리정수와의 비교와 함께 이하에 나타내었다. (표 1 참조).In the final step method, since the degree of hydrolysis of anti-isomers is higher than that of syn-isomers, the isomers are selectively hydrolyzed and removed. The reaction for hydrolyzing the ester bond of the compound (V) with or without 2-amino group is usually in the temperature range of 0 ° C to room temperature in the presence of 1 molar equivalent to molar equivalent of an alkali metal hydroxide such as potassium hydroxide or sodium hydroxide, And water or a water-miscible organic solvent such as methanol, ethanol, acetone, tetrahydrofuran, dioxane, N, N-dimethylformamide or N, N-dimethylacetamide and water. When R 6 is hydrogen in compound (V), the isolated syn-isomer can be converted to the syn-isomer of compound (V) in which R 6 is methyl by methylating this compound (V). This methylation reaction is carried out in a solvent under ice cooling or at a temperature near room temperature, and in most cases the reaction termination time takes several minutes to several hours. As a kind of solvent used for this purpose, any solvent which does not inhibit reaction may be sufficient. Thus, for example, tetrahydrofuran, dioxane, methanol, ethanol, chloroform, methylene chloride, ethyl acetate, butyl acetate, N, N-dimethylformamide, N, N-dimethylacetamide, water and mixtures of these solvents You can predict Examples of the methylating agent include methyl halides such as methyl oxide and methyl embrittlement, dimethyl sulfate, and diazomethane. In all cases except when diazomethane is used, the compound (V) which is this hydrogen is in the presence of a base such as an alkyl metal carbonate (sodium carbonate, potassium carbonate, etc.) or an alkali metal hydroxide (sodium hydroxide, potassium hydroxide, etc.). React with methylating agents. The physical constants of the syn-isomers of compound (III) and thus obtained compound (V) are shown below with comparison with the physical constants of the corresponding anti-isomers.

"syn" 이성체 중의 메톡시아미노(히드록시이미노)는 카르복실기에 대하여 시스이고, "anti" 이성체 중에 있는 것은 카르복실기에 대하여 트랜스이다.The methoxyamino (hydroxyimino) in the "syn" isomer is cis relative to the carboxyl group and the one in the "anti" isomer is trans relative to the carboxyl group.

(Ⅱ). 화합물(Ⅲ)(syn- 이성체)의 선택적 제조법은 이하에 설명될 것이다. 따라서, 전술한 화합물(Ⅶ)과 티오우레아와의 반응에 의하여 화합물(Ⅴ)의 anti- 이성체와 syn-이성체와의 혼합물이 수득되는데, 대개의 경우 화합물(Ⅴ)의 anti- 이성체가 많다. 이 환하 반응의 조건에 대한 본 발명자의 연구에 의하여 소기의 syn- 이성체의 선택적 생성을 유도하기 위한 조건을 알게 되었다. 그러므로, 화합물(Ⅴ)을 얻기 위하여 화합물(Ⅳ)과 티오우레아와의 반응을 이미 앞에서 설명한 조건하에 실시한다면, syn- 및 anti- 이성체는 통상 2 : 98 내지 50 : 50의 비율로 생성된다.(II). The selective preparation of compound (III) (syn-isomer) will be described below. Therefore, a mixture of the anti- and syn-isomers of compound (V) is obtained by the reaction of compound (VII) and thiourea as described above, and in many cases, the anti- isomers of compound (V) are many. The inventor's study of the conditions of this ring reaction revealed the conditions for inducing the selective production of the desired syn-isomer.

이 가수분해 반응은 광산 존재중에서 원활하게 일어나고, 용매 중에서는 정상적으로 수행된다. 상기 광산의 예로서는 염산, 황산, 인산 등에 있다. 용매는 반응을 저해하지 않는 종류의 것이면 좋다. 그 예로는 테트라히드로푸란, 디옥산 등의 에테르류, 메타놀, 에타놀 등의 알코올류, 및 이들 용제의 혼합물이 있다. 일반적으로, 이 반응은 빙냉하 또는 실온에서 실시될 수 있다. 출발물질(Ⅶ)은 R6이 수소이고 제2 위치의 아미노기가 보호된 일반식(Ⅴ)의 화합물 메틸화시켜 얻을 수 있다.This hydrolysis reaction takes place smoothly in the presence of a mine, and is normally performed in a solvent.
