A first embodiment of the invention relates to novel carbapenem compounds, (1R, 5S, 6S)-2-\x9b1-(1,3-thiazolin-2-yl)azetidin-3-yl!thio-6-\x9b(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 \x9b1-(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.
该发明的第一实施例涉及新型碳青霉烯化合物,(1R, 5S, 6S)-2-\x9b1-(1,3-噻唑啉-2-基)氮杂环丙氨基-3-基!硫基-6-\x9b(R)-1-羟基乙基!-1- 甲基碳青霉烯-2-酮-3-羧酸衍生物。这些碳青霉烯化合物由以下公式表示,其中在1位引入了一个β-配位的甲基基团,在2位引入了一个\x9b1-(1,3-噻唑啉-2-基)氮杂环丙氨基-3-基!硫基团。在公式中,R为氢;未被替代或被羟基、低烷氧基或低烷氧基-低烷氧基基团替代的低烷基基团;基团--COOR.sup.1(R.sup.1为氢或低烷基基团);或基团--CONR.sup.2 R.sup.3(R.sup.2和R.sup.3分别独立地为氢或低烷基基团),Y为羧基、--COO.sup..crclbar.或保护羧基。这些化合物对于预防和治疗细菌感染非常有用。该发明的第二实施例涉及3-巯基-1-(1,3-噻唑啉-2-基)氮杂环丙烷,其由以下公式及其酸盐表示,并提供其生产工艺。上述化合物作为制备碳青霉烯化合物的中间体非常有用,这些化合物具有强大的抗菌活性,方便且产率高。
