    • A first embodiment of the invention relates to novel carbapenem compounds, (1R, 5S, 6S)-2-�1-(1,3-thiazolin-2-yl)azetidin-3-yl!thio-6-�(R)-1-hydroxy-ethyl!-1-methylcarbapen-2-em-3-carboxyic acid derivatives. These carbapenem compounds are represented by the following formula having a beta-coordinated methyl group introduced at the 1-position and a �1-(1,3-thia-zolin-2-yl)azetidin-3-yl!thio group introduced at the 2-position. ##STR1## In the formula, R is hydrogen; lower alkyl group which is unsubstituted or substituted by hydroxy, lower alkoxy or lower alkoxy-lower alkoxy group; group --COOR.sup.1 (R.sup.1 is hydrogen or lower alkyl group); or group --CONR.sup.2 R.sup.3 (R.sup.2 and R.sup.3 are, independently each other, hydrogen or lower alkyl), and Y is carboxy, --COO.sup..crclbar. or protected carboxy. These compounds are useful antibiotics for prevention and treatment of bacterial infections. The second embodiment of the invention relates to 3-mercapto-1-(1,3-thiazolin-2-yl)azetidine represented by the following formula and its acid addition salts ##STR2## and to the production process therefor. The above compounds are useful as intermediates for preparing carbapenem compounds, which have strong antibacterial activity, with convenience and high yield.
    • 本发明的第一个实施方案涉及新的碳青霉烯化合物,(1R,5S,6S)-2- [1-(1,3-噻唑烷-2-基)氮杂环丁烷-3-基]硫基-6 - [(R) -1-羟基 - 乙基] -1-甲基碳代青霉-2-烯-3-羧酸衍生物。 这些碳青霉烯类化合物由下式表示:在1-位引入的β-配位甲基和[1-(1,3-硫杂 - 唑啉-2-基)氮杂环丁烷-3-基]硫基引入到 2位。 在该式中,R是氢; 低级烷基,未取代或被羟基,低级烷氧基或低级烷氧基 - 低级烷氧基取代; 基团-COOR1(R1是氢或低级烷基); 或基团-CONR 2 R 3(R 2和R 3彼此独立地为氢或低级烷基),Y为羧基,-COO( - )或被保护的羧基。 这些化合物是预防和治疗细菌感染的有用的抗生素。 本发明的第二个实施方案涉及由下式表示的3-巯基-1-(1,3-噻唑啉-2-基)氮杂环丁烷及其酸加成盐及其制备方法。 上述化合物可用作制备碳青霉烯类化合物的中间体,其具有强的抗菌活性,方便性和高产率。
