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.

标题:Method for synthesis of n-homocysteine thiolactonyl retinamide
发明人：KAZIMIR MICHAEL; WILSON RAY E II
权利人:UNIV BAYLOR; KAZIMIR MICHAEL; WILSON RAY E II
摘要:The present invention describes methods of synthesis for N-homocysteine thiolactonyl retinamide (thioretinamide), a compound that has anticancer and antiatherogenic properties. The present invention further describes methods for the synthesis of N-homocysteine thiolactonyl retinamido cobalamin (thioretinaco), a compound that has potential anticancer, antineoplastic, antiviral, and antiatherogenic properties.

摘要:Compounds being analogues of a dipeptide in which the nitrogen atom of the linking amide group of the dipeptide is replaced by trivalent group ##STR1## and in which, optionally, the carbonyl function of this linking group is replaced by the divalent group --CH 2 -- are of value in the synthesis of isosterically modified peptides.

标 题:Catalyst for synthesis of vesicular phenoxy resins
发明人：BENNETT EVERETT W
权利人:JAMES RIVER PAPER CO
摘要:A catalyst for synthesis of vesicular phenoxy resins is disclosed. The catalyst includes a water-insoluble complex of a hydric phenol and a quaternary ammonium or phosphonium salt of the hydric phenol. Preferably, the hydric phenol is an intermediate of the phenoxy resin being produced. Dihydric phenols, such as sulfonyldiphenol are preferred. The invention further relates to a reaction medium for polymerization of phenoxy resins including the above-described catalyst and a solvent medium capable of dissolving the phenoxy resins and otherwise not interfering with the polymerization reaction. The solvent medium is advantageously free of toxic Methyl Cellosolve.

标 题 :Method for reducing microcontaminants during synthesis of pentachlorophenol
发明人：SAVAGE PHILLIP E; YU JIANLI
权利人:UNIV MICHIGAN
摘要:A method for reducing contaminants during synthesis of pentachlorophenol includes providing a phenol-based starting material and a catalyst, which form a reaction mixture. A chlorine flow is introduced so that it is in contact with the reaction mixture, and the starting material and chlorine are reacted via a temperature-programmed reaction. The chlorine flow is terminated at a predetermined temperature prior to an end of the temperature-programmed reaction and/or at a point where the yield of pentachlorophenol is less than about 95%.

摘要:Novel processes towards the synthesis of the antiviral valomaciclovir stearate in which an esterified guanine acetal is reduced to the corresponding alcohol, reacted with an activated amino acid and N-deprotected. The esterified guanine acetal is prepared from a 9-guanine derivative bearing an acyclic hydroxymethylbutylacetal. The processes are amendable to one-pot reactions.
