摘要: A process for the oxidation of organosulphur compounds with hydrogen peroxide is provided. The process employs solid supported polyacids comprising tungsten, molybdenum and/or vanadium as catalysts. The supports are selected from compounds, preferably oxides, of Group IIa, IIb, IIIb, IVa and IVb elements, and strong base ion exchange resins. Certain embodiments of the process provide for the oxidation of sulphides to sulphoxides or sulphones, particularly for the oxidation of penicillins to penicillin sulphoxides. Other embodiments of the process provide for the selective oxidation of thiols to sulphoxides.

摘要: 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.
