    摘要: The present invention provides a labelled .beta.-cyano-L-alanine and a .gamma.-cyano-.alpha.-aminobutyric acid, of which cyano group carbon is labelled with radionuclide .sup.11 C or .sup.14 C, or stable isotope .sup.13 C. The present invention also provides a labelled amino acids such as asparagine, asparatic acid, DABA, GABA, glutamine and glutamic acid synthesized by using the labelled .beta.-cyano-L-alanine and the .gamma.-cyano-.alpha.-aminobutyric acid as an intermediate. The labelled amino acids are useful for in vivo imaging of tumors and brain functions.

    摘要: A process for the preparation of a 1,8-bridged 4-quinolone-3-carboxylic acid of the formula ##STR1## comprising in a first reaction step reacting an enamine of the formula ##STR2## in an anhydrous, aprotic solvent with one equivalent of a base, at a temperature form 80.degree. C. to 180.degree. C., to give a 4-quinolone-3-carboxylic acid derivative of the formula ##STR3## and, in a second reaction step, reacting that with another equivalent of a base, to give the 1,8-bridged 4-quinolone-3-carboxylic acid derivative of the formula (I) and optionally converting the group Y into a carboxyl group or salt thereof. Both steps may be effected simultaneously in a one-pot process without intermediate isolation of the compound II. Some of the compounds are new. The old and new compounds are antibacterials and promote animal growth.

    摘要: 3,3,5-Trichloroglutaric acid imide can be produced either by reacting a trichloroacetic acid alkyl ester, in the presence of a catalyst, with acrylonitrile to the corresponding 2,2,4-trichloro-4-cyanobutyric acid alkyl ester, converting this into the amide, and cyclizing the 2,2,4-trichloro-4-cyano-butanecarboxylic acid amide, in an aqueous acid medium, to the 3,3,5-trichloroglutaric acid imide; or by reacting trichloroacetonitrile, in the presence of a catalyst, to 2,2,4-trichloro-4-cyanobutyronitrile, and cyclizing this, in an aqueous acid medium, to 3,3,5-trichloroglutaric acid imide. The catalyst used for the addition reactions can be for example copper(I) chloride or copper(II) oxide. 3,3,5-Trichloroglutaric acid imide can be converted, by treatment with a dehydrating chlorinating agent, such as POCl.sub.3, into the known 2,3,5,6-tetrachloropyridine, which for its part is used for producing various active substances, particularly insecticides, herbicides and fungicides.
