标 题:Solid-phase synthesis of N-alkyl amides
发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.

标题 :Aerobic Oxidative Esterification of Sugar-Derived 1,4-Disubstituted Benzene for Direct Synthesis of Dimethylterephthalate
发明人：SHIRAMIZU MIKA; LATTNER JAMES R; KANDEL KAPIL
权利人:EXXONMOBIL CHEM PATENTS INC
摘要:This invention relates to a dimethylterephthalate production process comprising reacting substituted furan with ethylene under cycloaddition reaction conditions and in the presence of a cycloaddition catalyst to produce a bicyclic ether, dehydrating the bicyclic ether to produce a substituted phenyl, dissolving said substituted phenyl in methanol, and oxidizing and esterifying the substituted phenyl in the presence of an oxidative esterification catalyst to form dimethylterephthalate. Importantly, the process does not include oxidizing the substituted phenyl to form terephthalic acid.

权利人:UNIV NORTH CAROLINA STATE
摘要:A (preferably nonaqueous) method of making a dipyrromethane is described. The comprises the steps of: (a) providing a reaction system consisting essentially of an aldehyde or acetal, excess pyrrole and a catalyst; (b) reacting the aldehyde or acetal with the pyrrole in the reaction system to form the dipyrromethane therein; (c) quenching the reaction system by adding a base thereto (preferably without simultaneously or concurrently adding water and/or an organic solvent thereto); (d) separating the catalyst from the reaction system; and then (e) separating the pyrrole from the reaction system to produce the dipyrromethane as a residual

标题 :Polymeric self-assembly multiplayer membranes for ion screening: design, fabrication and application in sensors
发明人：ZHOU JICANG; LI QING
权利人:HONEYWELL INT INC
摘要:The embodiments of the invention are related to an extrinsically compensated multilayer membrane comprising at least a first layer comprising charged polymers and a second layer comprising neutral polymers, wherein the first layer is characteristic of extrinsic compensation and the charges on the polymer are balanced by mobile counter ions. The embodiments of the invention relate to: i) extrinsically compensated membrane for ion screening; ii) two types of polymers for fabricating the extrinsically compensated membrane; iii) driving force for self-assembly and approaches to create such a driving force between the two polymers, which involve the functionalization of the two types of polymers via functional moieties: donors and acceptors; iv) one or more approaches of synthesis of the two types of polymers; v) the fabrications of extrinsically compensated membrane with the two types of polymers; and vi) the fabrication of functional sensing membranes and the sensors thereof.
