vicinal oxygen atoms to the reactive group able to build a hydrogen bonding network with the reactant. The role of carbon dioxide and hexafluoroisopropanol was investigated to support the hypothesis that a template catalysis effect is occurring. The in vitro anti-fungal activity of some of these derivatives was tested on two plant fungi, Botrytis cinerea and Penicillium species, with moderate activity.
在温和的条件下,没有溶剂和催化剂的情况下,直接高收率合成了十一种新颖的单取代的二茂铁基甲基醚和二茂铁甲醇和邻位氧化的醇和胺的胺衍生物。这些类型的非酸性化合物促进脱水亲核取代的独特能力归因于附近的氧原子存在于能够与反应物建立氢键网络的反应性基团上。研究了二氧化碳和六氟异丙醇的作用,以支持正在发生模板催化作用的假设。在两种植物真菌灰葡萄孢和青霉菌上测试了其中一些衍生物的体外抗真菌活性。 种,活动适中。
