    • 2-Carboxymethyl-3-carboxy-chromones and esters of the formula ##STR1## in which R, R.sup.1 and R.sup.2 each independently is hydrogen, an optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aralkyl or aryl group, halogen, hydroxyl, cyano or an optionally substituted alkoxy, aryloxy, aralkoxy, alkoxy-carbonyl or dialkylamino group, orR and R.sup.1, together with two carbon atoms of the benzene ring system, form a carbocyclic or heterocyclic 5-membered or 6-membered ring, andR.sup.3 is hydrogen, optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl or aralkyl,are characterized by fungicidal and arthropodicidal activities. The novel compounds are produced by reacting an o-hydroxyacetophenone of the formula ##STR2## with a glyoxylic acid derivative of the formulaOCH--COOZin whichZ is a cation,in the presence of a basic compound, followed by acidification to form the dicarboxylic acid and, optionally, the ester.
    • 2-羧甲基-3-羧基 - 色酮和式“IMAGE”的酯,其中R,R 1和R 2各自独立地为氢,任选取代的烷基,烯基,环烷基,环烯基,芳烷基或芳基,卤素,羟基,氰基 或任选取代的烷氧基,芳氧基,芳烷氧基,烷氧基 - 羰基或二烷基氨基,或R和R 1与苯环体系的两个碳原子一起形成碳环或杂环的5元或6元环,并且R 3为 氢,任选取代的烷基,烯基,环烷基,环烯基或芳烷基,其特征在于杀真菌和节肢动物杀虫活性。 通过在碱性化合物的存在下,使式“IMAGE”的邻羟基苯乙酮与其中Z为阳离子的式OCH-COOZ的乙醛酸衍生物反应,然后酸化形成二羧酸 酸和任选的酯。

    • Compounds useful in the treatment of cholesterolaemia are of the general formula ##STR1## or salts thereof in which R.sup.1 and R.sup.2 independently denote radicals including hydrogen, alkyl, aryl and heterocyclic radical or together complete a carbocyclic or heterocylic ring, R.sup.3 denotes a radical ##STR2## in which R.sup.9, R.sup.10 and R.sup.11 include hydrogen, cyano, nitro, alkyl and aryl or, in pairs, complete carbocyclic rings, X denotes cyano, nitro or substituted carbonyl, sulphonyl or phosphonyl group, R.sup.4 is hydrogen or a radical defined for R.sup.1 or R.sup.3, and R.sup.5, R.sup.6, R.sup.7 and R.sup.8 include hydrogen, nitro, cyano, carboxyl, alkyl and aryl or, in pairs, complete carbocyclic rings, with the proviso that R.sup.1 and R.sup.9 are not both phenyl if X denotes CO--C.sub.6 H.sub.6. The compounds exhibit considerably higher hypocholesterolaemic activity than the known clofibrate and in addition exhibit a pronounced nutritive effect, e.g., in a medicated fodder or premix.
    • 用于治疗胆固醇血症的化合物具有通式(I)或其盐,其中R 1和R 2独立地表示包括氢,烷基,芳基和杂环基团的基团,或者一起完成碳环或杂环,R3表示 其中R9,R10和R11包括氢,氰基,硝基,烷基和芳基,或成对地成为完全碳环,X表示氰基,硝基或取代的羰基,磺酰基或膦酰基,R4是氢或基团 对于R 1或R 3而言,R 5,R 6,R 7和R 8包括氢,硝基,氰基,羧基,烷基和芳基,或成对地成为完全碳环,条件是如果X表示CO,则R 1和R 9不是苯基 -C6H6。 化合物显示比已知的氯贝特明显更高的降血胆固醇血症活性,并且还显示出明显的营养作用,例如在药物饲料或预混物中。
