标题:利用二级配位球相互作用实现苄基 C-H 键的选择性酰胺化
摘要:工程位点选择性是非常需要的,尤其是在 Ch 官能化反应中.我们报告了一种新的催化剂平台,该平台对由二级配位球中的 π-π 相互作用控制的苄基 Ch 键的酰胺化具有高度选择性.对先前开发的铱催化剂显示出较差的区域选择性的机理理解引起了这样的认识,即基底上芳香族片段的 π 云可以通过与催化剂的双齿配体的有吸引力的非共价相互作用充当正式的导向基团. 基于这种机制驱动的策略,我们开发了一种带有中性多吡啶基配体的阳离子 (η5-C5H5)Ru(II) 催化剂,在同时存在叔 Ch 键的情况下,在分子内 Ch 内酰胺化中获得了创纪录的苄选择性.距离.结合实验和计算技术来确定这种前所未有的苄基选择性的起源,并且发现溶剂极性指数和测得的位点选择性之间稳健的线性自由能关系清楚地证实了疏溶剂效应驱动了选择性.证明了反应范围的普遍性和对多功能 γ-内酰胺合成的适用性.

摘要:Process for purifying 7-substituted aminodeacetoxycephalosporins through the use of filter membranes. A process for purification by ultrafiltration and/or nanofiltration with a cut-off for molecular weights over 10,000 Dalton and preferably over 2000 Dalton is described. For example cephalosporin-G of increased purity, represented by a 6-8% increase in the HPLC titre, with a reduction of 50% in absorbance, is obtained using this technique. The invention makes it possible for the purified products to be used directly in the synthesis of other antibiotic compounds without the need for intermediate isolation. ##STR1##

标题:System and method for early detection for prevention of postharvest chilling injury
发明人：NOAM ALKIN
权利人:US AGRICULTURE; NOAM ALKIN
摘要:Aspects of the present invention include detection of volatile compounds related to response of vegetable or fruit, (e.g., mango), as result of stress like suboptimal temperature. Such response may lead to activation of some metabolic pathways that can induce synthesis of volatile compounds which may serve according to embodiments of the present invention as signals which indicate onset of CI and/or deterioration of fruit quality. The release of such volatiles compounds may be detected long before CI symptoms become notable. According to some embodiments of the invention, output from sensors detecting presence of volatile compounds indicating that fruits are starting to suffer from chilling stress, are received by at least one control module which operates conditioning system so as to alter storage conditions for avoiding CI and/or quality deterioration of fruits or vegetables.

摘要:According to the invention, there is provided null-LOX-1 barley and plant products produced thereof, such as malt manufactured by using barley kernels defective in synthesis of the fatty acid-converting enzyme lipoxygenase-1. Said enzyme accounts for the principal activity related to conversion of linoleic acid into 9-hydroperoxy octadecadienoic acid, a lipoxygenase pathway metabolite, which-through further enzymatic or spontaneous reactions-may lead to the appearance of trans-2-nonenal. The invention enables brewers to produce a beer devoid of detectable trans-2-nonenal-specific off flavors, even after prolonged storage of the beverage.

摘要:The present invention provides novel compounds exemplified by pyrrolic nitrogens used as anion and neutral species recognition elements with an aromatic core as a signal group. Described are methods for the synthesis of various pyrrole aryl compounds as well as various applications for these compounds. Methods of use include the binding and detection of specific analytes in a mixture and, in some examples, the separation of the analyte from the mixture. Additional methods of use include the transport of therapeutic agents and the sensing of components, degradants, and impurities in foodstuffs.
