  • Chemoenzymatic process for production of S fenpropimorph
    申请人:CAFFARO S.p.A. Società per l'Industria Chimica ed Elettrochimica
    公开号:EP0645458A1
    公开(公告)日:1995-03-29
    A process for stereoselective (enantioselective) production of S-(-)-fenpropimorph, which process comprises reacting 4-tert-butylbenzylchloride or bromide with methyldiethylmalonate, decarbethoxylation of the product into racemic 3-(4-tert-butylphenyl)-2-methylpropionic acid ethyl ester in DMSO in the presence of alkali cations, then Pseudomonas sp. lipase catalyzed resolution of racemic ester to S-(-)-acid, base-catalyzed racemisation and recycling of the R-(+)-ester, acylation of cis-2,6-dimethylmorpholine with the activated derivative of S-(-)-acid, and final reduction of the intermediary amide to provide optically (enantiomerically) pure S-(-)-fenpropimorph. The key enzymatic reaction is fast, employs inexpensive commercially available enzyme, requires minimal work-up, and can therefore easily be performed on a large scale.
    一种选择性立体异构体(对映选择性)生产S-(-)-芬普莫尔的过程,该过程包括将4-叔丁基苯甲基氯化物或溴化物与甲基二乙基丙二酸酯反应,将产物在DMSO中与碱金属阳离子存在下脱乙酰基成为外消旋的3-(4-叔丁基苯基)-2-甲基丙酸乙酯,然后通过假单胞菌脂肪酶催化将外消旋酯分离为S-(-)-酸,碱催化的消旋反应并回收R-(+)-酯,用激活的S-(-)-酸衍生物对顺式-2,6-二甲基吗啡进行酰化,最后还原中间酰胺以提供光学(对映)纯的S-(-)-芬普莫尔。关键的酶催化反应速度快,使用廉价的商业酶,需要最少的后处理工作,因此可以轻松地进行大规模生产。
  • Fiber optic potassium ion sensor
    申请人:Hewlett-Packard Company
    公开号:EP0484865A2
    公开(公告)日:1992-05-13
    A sensor (10) is provided for detecting the concentration of potassium ions which comprises a molecule which selectively complexes potassium ions. The molecule, e.g., 2,2-bis[3,4-(15-crown-5)-2-nitrophenylcarbamoxymethyl]tetradecanol-14, has at least one binding site and is provided with a fluorophore group, e.g., Rhodamine-B, at that site. The molecule is one that expands upon complexation of potassium ions, such that the intensity of fluorescence increases. The change in fluorescent intensity is a direct measure of the concentration of potassium ions. A detector employing the sensor is also provided.
    本发明提供了一种用于检测钾离子浓度的传感器(10),该传感器由一种能选择性络 合钾离子的分子组成。该分子,例如 2,2-双[3,4-(15-冠-5)-2-硝基苯基氨基甲酰氧甲基]十四醇-14,具有至少一个结合位点,并在该位点上具有荧光基团,例如罗丹明-B。这种分子在与钾离子络合时会膨胀,从而使荧光强度增加。荧光强度的变化可直接测量钾离子的浓度。此外,还提供了一个采用该传感器的检测器。
