    • The acetylmethyl ester of hetacyllin and/or its salts of an organic or inorganic acid are described and methods for their synthesis wherein a tertiary amine and chloroacetone are introduced to hetacyllin in an organic solvent or chloroacetone is introduced to hetacyllin in the form of a salt with an alkali metal in an organic solvent, and then from the reaction mixture, the acetylmethyl ester of hetacyllin is isolated in free form and, if desired, a salt of the ester is obtained by reaction with an organic or inorganic acid in an organic solvent.As tertiary amines, trialkylamine, N-methylpiperidine, N-ethylpiperidine or N-methylmorpholine are used; as organic solvents in obtaining the ester, dimethylformamide, dimethylacetamide or dimethylsulfoxide are used. In obtaining salts of the ester the organic solvents used are aliphatic alcohols of a chain length C.sub.2 -C.sub.5 ; ketones, preferably acetone; ethers, such as diethyl, dipropyl, diisopropyl, dibutyl ethers, or their mixtures.The obtained compounds show an antibacterial action like ampicillin but after administration per os they show a considerably higher level of the antibiotic than that after administration of free ampicillin or its esters.
    • 描述了hetacyllin的乙酰甲基酯和/或其有机或无机酸的盐,并将其合成方法,其中叔胺和氯丙酮在有机溶剂或氯丙酮中引入hetacyllin,以盐的形式引入到hetacyllin中, 在有机溶剂中的碱金属,然后从反应混合物中分离出游离形式的海参酰基乙酰甲基酯,如果需要,通过在有机溶剂中与有机或无机酸反应获得酯的盐。 作为叔胺,使用三烷基胺,N-甲基哌啶,N-乙基哌啶或N-甲基吗啉; 作为获得酯的有机溶剂,使用二甲基甲酰胺,二甲基乙酰胺或二甲基亚砜。 在获得酯的盐时,使用的有机溶剂是链长C 2 -C 5的脂族醇; 酮,优选丙酮; 醚,如二乙基,二丙基,二异丙基,二丁基醚或它们的混合物。 所得化合物显示出抗菌作用,如氨苄青霉素,但是在施用之后,它们显示比施用游离氨苄青霉素或其酯后显着高得多的抗生素水平。
