摘要:氯代芳烃的电化学还原与供电取代基(如氯甲苯,-苯甲醚和-酚)进行研究.在铅或碳阴极下,在各种溶剂支持电解质的电位静态和电流静态条件下进行制备电解.在适当条件下,可能对具有两个或更多氯取代基的化合物进行部分和主要区域选择性的去氯化.尤其是在对位,替换一个单独的氯取代基是困难的.因此,高度有毒和持久的寡氯衍生物可以转化为氯化程度较低的问题较少的化合物.通过电还原,也可以显着降低受氯化酚和nitrofen®污染的土壤提取物等实际材料的氯含量.

权利人:KABIR ABUZAR; FURTON KENNETH G; THE FLORIDA INTERNATIONAL UNIV BOARD OF TRUSTEES
摘要:The subject invention provides chemical compositions and synthesis strategies to create molecularly imprinted polymers (MIPs) via sol-gel processes. In a specific embodiment, the subject invention utilizes a(n) organic, inorganic, or metallic template analyte to create a hybrid organic-inorganic or inorganic three-dimensional network possessing cavities complementary to the shape, size, and functional orientation of the template molecule or ions. The subject invention further pertains to the use of the novel MIPs as selective solid phase extraction (SPE) sorbents for pre-concentration and clean-up of trace substances in biological and environmental samples. Synthesis of other molecularly imprinted polymers with environmental, pharmaceutical, chemical, clinical, toxicological, and national security implications can be conducted in accordance with the teachings of the subject invention.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

摘要:A process for the production of a monochloromethyl ketone of the formula in which R1, R2 and R3 each independently is a hydrogen atom or an optionally substituted alkyl, alkenyl, alkinyl or aryl radical, or R1 and R2 together with the carbon atom to which they are attached form an optionally substituted carbocyclic ring, comprising reacting a 1,1-dichloroalkene of the formula with a phenolate of the formula in which R4 each independently is a halogen atom, a nitro group, or an optionally substituted alkyl, alkoxy or aryl radical, n is 0, 1, 2 or 3, and M is one equivalent of an alkali metal ion or alkaline earth metal ion, thereby to obtain a phenyl ether intermediate, and then subjecting the phenyl ether intermediate to an acid hydrolysis. The products are useful as intermediates in the synthesis of fungicides.
