    肉桂酸衍生物及其杂芳环类似物作为潜在的高效杀青霉菌的生物活性和结构-活性关系
    摘要:
    合成了一系列肉桂酸衍生物及其杂芳族环类似物,并评价了其对against螨(Psoroptes cuniculi)的体外杀螨活性。其中,有8种化合物显示出更高的活性,中位致死浓度(LC 50)为0.36–1.07 mM(60.4–192.1 µg / mL),并且具有开发新型杀螨剂的巨大潜力。化合物40的最低LC 50值为0.36 mM(60.4 µg / mL),最小中值致死时间(LT 50)在4.5 mM时为2.6 h,与伊维菌素相当[LC 50  = 0.28 mM(247.4 µg / mL) ,LT 50 = 8.9 h],这是一种杀螨药物标准。SAR分析表明,羰基对活性至关重要。酯部分中烷氧基的类型和链长以及酯基附近的空间位阻显着影响活性。该酯比相应的硫羟酸酯,酰胺,酮或酸更具活性。用α-吡啶基或α-呋喃基取代肉桂酸酯的苯基会显着提高活性。因此,出现了一系列具有优异杀螨活性的肉桂酸酯及其杂芳族环类似物。

  • Single step green process for the preparation of substituted cinnamic esters with trans-selectivity
    申请人:Sinha Kumar Arun

    公开(公告)日:2008-02-21
    The invention provides a green process for direct oxidation of a large number of substituted or unsubstituted cinnamaldehydes or cinnamyl alcohols into the corresponding alkyl or aryl cinnamates in one step. The process of the present invention is a convenient and efficient green process for the preparation of various aryl or alkyl cinnamates under conventional, microwave and ultrasound directly from cinnamaldehydes or cinnamyl alcohols in the presence of an oxidizing agent, catalyst and an alcohol, with or without an organic solvent. These esters are immensely important compounds in flavor, perfumery and pharmaceutical industries. There are several prior arts available for the preparation of cinnamic esters, but all of them suffer from deficiencies such as use of expensive reagents and catalysts, harsh reaction conditions, use of toxic chemicals and others. In contrast, the present methodology is extremely simple and involves reaction of the substrate with an oxidizing agent mixed with a homogeneous or heterogeneous catalyst and an alcohol with or without organic solvent by stirring at room temperature or refluxing or under microwave or ultrasound irradiation to get the requisite products.
    本发明提供了一种绿色工艺,用于将大量取代的或未取代的肉桂醛或肉桂醇直接氧化成相应的烷基或芳基肉桂酸酯的一步法。本发明的过程是一种方便有效的绿色工艺,可以在常规、微波和超声波条件下,在氧化剂、催化剂和醇的存在下,直接从肉桂醛或肉桂醇制得各种芳基或烷基肉桂酸酯,可使用或不使用有机溶剂。这些酯类化合物在香料、香精和医药行业中具有极其重要的作用。尽管存在一些用于制备肉桂酸酯的现有技术,但它们都存在诸如使用昂贵的试剂和催化剂、反应条件苛刻、使用有毒化学品等缺陷。相比之下,本方法极为简单,涉及将底物与氧化剂混合均相或非均相催化剂和醇,在有机溶剂存在下或不存在的条件下,通过在室温下搅拌或回流或微波或超声波照射下反应,以得到所需产品。
  • A dramatic effect of the ionic liquid structure in esterification reactions in protic ionic media

    Brønsted acidic ionic liquids (ILs) have been synthesized and investigated as catalysts in esterification and transesterification reactions: simple and non-corrosive salts characterized by aliphatic cations associated with an “acidic” anion (in particular, [HSO4]−) gave the higher yields. A quite good correlation between IL acidity (H0) and catalytic ability was found although also the hydrophilic nature of the ionic medium probably affects the process efficiency.
    研究了作为酯化和转酯化反应催化剂的Brønsted酸性离子液体(ILs)的合成和性能:由脂肪族阳离子与“酸性”阴离子(特别是[HSO4]−)组成的简单且无腐蚀性的盐,在反应中得到了较高的产率。虽然离子介质的亲水性也可能影响过程的效率,但在离子液体酸度(H0)与催化能力之间发现了一个相当良好的相关性。

    Cinnamic, p-coumaric and ferulic acids were isolated from pineapple stems (Ananas comosus var. Cayenne). Twenty-four kinds of esters were prepared from these acids, alcohols and the components of Alpinia. Isopropyl 4-hydroxycinnamate (11) and butyl 4-hydroxycinnamate (12) were found to have almost the same effectiveness in antifungal activity against Pythium sp. at 10 ppm as that of the commercial
    从菠萝茎(Ananas comosus var。Cayenne)中分离了肉桂酸,对香豆酸和阿魏酸。由这些酸,醇和高良姜的成分制得二十四种酯。发现4-羟基肉桂酸异丙酯(11)和4-羟基肉桂酸丁酯(12)在对抗腐霉菌属的真菌活性方面具有几乎相同的功效。含量为商业杀菌剂异丙苯酚(kitazin P)的10 ppm。
  • Bulky diarylammonium arenesulfonates as mild and extremely active dehydrative ester condensation catalysts
    作者:Akira Sakakura、Shoko Nakagawa、Kazuaki Ishihara
    DOI:10.1016/j.tet.2005.09.059
    日期:2006.1
    especially large-scale, fundamental reactions like ester condensations, are highly desirable for many reactions. Bulky diarylammonium pentafluorobenzenesulfonates and tosylates serve as extremely active dehydration catalysts for the ester condensation reaction of carboxylic acids with equimolar amounts of sterically demanding alcohols and acid-sensitive alcohols. Typically, the esterification reaction is performed
    对于许多反应,非常需要对当前化学方法更具环境友好性的替代方法,尤其是大规模的基本反应,如酯缩合。庞大的五氟苯磺酸二芳基铵盐和甲苯磺酸盐是非常有效的脱水催化剂,用于羧酸与等摩尔量的空间需求的醇和酸敏感性醇的酯缩合反应。典型地,酯化反应是在庚烷中,在1mol%催化剂的存在下,在80℃下加热进行的,而不除去水。即使在室温下,也可以在没有溶剂的情况下使用伯醇进行酯化。此外,与4-(N-间苯二甲氨基)聚苯乙烯树脂结合的五氟苯磺酸盐可以循环使用超过10次而不会损失活性。
