楼主的内容专业单词多了些,呵呵。Communication通讯Total Synthesis of (−)-Penifulvin A, an Insecticide with a Dioxafenestrane SkeletonPenifulvin A,一种采用二氧四环壬烷(Dioxafenestran)骨架的杀虫剂的全合成Abstract摘要Herein we report the first total synthesis of Penifulvin A, a sesquiterpenoid with a novel dioxa-fenestrane structure. 以下我们报道Penifulvin A的首次全合成,这是一种具有全新二氧四环壬烷结构的倍半萜化合物。Penifulvin A is a potent insecticide against the fall armyworm Spodoptera frugiperda which causes enormous damage in the US by consuming foliage of a variety of field crops. Penifulvin A是一种针对草地贪夜娥(Spodoptera frugiperda)的专利杀虫剂,这种昆虫由于消耗多种野外庄稼的叶子而在美国造成巨大的损害。A five-step racemic and an eight-step enantioselective route to the natural product and the determination of its absolute configuration are described. 描述了对于天然产物的一个五步的外消旋和一个八步的对映选择路线,以及对其绝对构型的确定。The key step involves a meta-photocycloaddition, giving rapid access to the carbon skeleton of penifulvin A in a stereoselective fashion. 关键的步骤涉及到间位-光环加成反应,从而以立体有择反应的方式迅速接入到Penifulvin A的碳骨架。Finally an oxidation cascade leads to the natural product. The synthetic route is free from protecting groups, scalable, and flexible so that a variety of analogues, among them penifulvins B−E, should be available for performing SAR tests in the insecticidal role.最后,氧化级联导致了这种天然的产物。该合成路线没有保护基团,可扩展,而且灵活,因此好多模拟产品(其中如PenifulvinB-E)应该可以获得而用于杀虫作用的SAR试验。Communication通讯Synthesis of Uniform Ferrimagnetic Magnetite Nanocubes均匀铁磁磁铁矿纳米单晶的合成Abstract摘要We synthesized uniform ferrimagnetic magnetite nanocubes in the size range from 20 to 160 nm. The magnetic property of the nanocubes was characterized, and magnetic separation of the histidine-tagged protein was demonstrated.我们合成了尺寸范围从20到160nm的均匀的铁磁磁铁矿纳米单晶。对这种纳米单晶的磁性质进行了表证,并实验演示了多聚组氨酸融合蛋白的磁分离。Communication通讯A Single Antibody Catalyzes Multiple Chemical Transformations upon Replacement of the Functionalized Small Nonprotein Components一种单一抗体在替代官能化小非蛋白成分中催化多种化学转化Abstract摘要A single antibody catalyzes multiple chemical transformations upon replacement of the funcctionalized small nonportein components.一种单一抗体在替代官能化小非蛋白成分中催化多种化学转化Communication通讯Supercritical Processing as a Route to High Internal Surface Areas and Permanent Microporosity in Metal−Organic Framework Materials作为在有机金属骨架材料中达到高内部表面积和永久性微孔率路线的超临界工艺AbstractCareful processing of four representative metal−organic framework (MOF) materials with liquid and supercritical carbon dioxide (ScD) leads to substantial, or in some cases spectacular (up to 1200%), increases in gas-accessible surface area. Maximization of surface area is key to the optimization of MOFs for many potential applications. Preliminary evidence points to inhibition of mesopore collapse, and therefore micropore accessibility, as the basis for the extraordinarily efficacious outcome of ScD-based activation摘要用液体和超临界二氧化碳(ScD)仔细加工四种代表性的金属-有机骨架(MOF)材料导致了气体进入表面积方面重大的(在某些情况下是惊人的(最高达1200%))增加。表面积的最大化是MOF材料在很多潜在应用中最优化的关键。初步证据指向抑制中孔的塌陷,因此也指向了微孔的可进入性,而这是ScD基活化异常有效结果的基础。
