摘要:已经开发出实用的双环二烯基sultam 9的合成方法.可行的路线涉及几个关键步骤.其中,以19转换为20表示的闭环复分解必须在其他环(例如15)中的组装之前进行.与16一样,将产品20用作更高级框架构建的模板.最好通过溴化-脱氢溴化顺序引入第二个双键,通过在ch 2 Cl 2或dmso中使用四正丁基氟化铵可最可靠地实现hbr的2倍损失.直接照射借助图9,可以得到内向型环丁烯衍生物30.标题二烯尚未准备好参与diels-Alder反应.x-射线晶体学分析证实,当将内-降冰片基三唑啉二酮在乙酸乙酯溶液中加热时,发生转化为33和其非对映异构体的1:1混合物.从机理的角度来看,这种转变构成了一个立体控制的和区域选择性的[2 + 2]环加成反应,然后进行乙烯基环丁烷-环己烯重排的有趣例子.产物30和33构成了具有降冰片基样结构成分的应变磺酰胺的实例.

标 题:Synthesis of acridinium compounds by N-alkylation of acridans
发明人：NATRAJAN ANAND; WEN DAVID
权利人:SIEMENS HEALTHCARE DIAGNOSTICS INC
摘要:A method is provided for N-alkylation of acridine compounds by reduction of acridines to corresponding acridans to improve the reactivity of the acridine nitrogen, and subsequent N-alkylation of the acridans in ionic liquid solvents to provide the corresponding acridinium compounds in high yield. This inventive process improves chemical conversion, and does not require the use of highly toxic alkylating agents, such as 1,3-propane sultone.

摘要:The present invention provides compounds used in the synthesis of chemiluminescent acridinium compounds and methods of producing these compounds. Specifically, methods are provided for the N-alkylation of acridan compounds using alkylating reagents. Typically, these alkylating reagents comprise a protected sulfonate group protected with an acid-labile protecting group.

摘要:A novel poly(arylene ether sulfone) having a sulfoalkoxy group, which has both of heat resistance and electroconductivity, is suitable as polymer electrolyte membranes used for high performance polymer electrolyte fuel cells, and does not use fluorine so that loads to the environment are small in the synthesis or disposal, a process of producing the same, and a polymer electrolyte membrane comprising the same. The poly(arylene ether sulfone) having a sulfoalkoxy group has a structural unit represented by the formula (1) mentioned hereinabove, and is produced by reacting a poly(arylene ether sulfone) having a hydroxyl group with a specific alkali metal compound and/or an organic base compound, followed by reacting with a specific sulfonating agent and then with a specific acid. A polymer electrolyte membrane is produced by film formation of the polymer.
