标题:面向稳定多色电致变色聚合物的扭曲共轭分子系统设计
摘要:共轭聚合物在电致变色器件中的有前途的进步要求设计一种高性能的电致变色聚合物,该聚合物在循环电负载下具有丰富的色彩转换和长期稳定性.在这里,我们报告了通过扭曲共轭分子工程开发具有非常好稳定性的多色电致变色聚合物的新策略.通过将邻亚烷基二氧苯与edot单元偶联,可以合成一系列扭曲的杂化前体,并且可以在相对较低的聚合电势下轻松地电合成其相应的聚合物.通过dft计算,光谱,形态,电化学和光谱电化学分析等系统地阐明了这种邻亚烷基二氧基苯-Edot杂化物前体和聚合物的结构-性质关系.我们证明,邻亚烷基二氧基苯与edot部分之间的二面角可实质上影响聚合物的电化学和电致变色性能.随着二面角和电子云密度的增加,这些杂化聚合物表现出独特的多种颜色切换特性和非常好的整体性能,包括较高的着色效率(> 200 Cm2 C-1),非常好的光学对比度(> 45%),快速开关(<1 S)和出色的开关稳定性(在3500次循环

标 题:Improved method of synthesis of 1-(3',4'-methylene dioxyphenyl)-2-(methylamino) propane (mdma)
发明人：O'MALLEY WILLIAM IAN; WYNNE PAUL MICHAEL
权利人:MIND MEDICINE AUSTRALIA LTD
摘要:The present invention relates to an improved method of synthesis of 1-(3',4'-methylenedioxyphenyl)-2-(methylamino)propane (MDMA) that is of sufficient purity that it can be used for pharmaceutical applications. In particular the present invention provides a method of synthesising MDMA comprising the steps of (a) condensation of piperonal and nitroethane in the presence of a catalysing base to form 1-(3',4'-methylenedioxyphenyl)-2-nitroprop-1-ene (MDP-2-nitropropene), (b) oxidative hydrolysis of MDP-2-nitropropene to form 1-(3',4'methylenedioxyphenyl)-propan-2-one (MDP2P), and (c) reductive amination of MDP2P to 1-(3',4'-methylenedioxyphenyl)-2-(methylamino)propane (MDMA).

标题 :Synthesis of α-chloro or fluoro ketones
发明人：DOLLING ULF H; FREY LISA F; TILLYER RICHARD D; TSCHAEN DAVID M
权利人:MERCK & CO INC
摘要:A simple, high yielding synthesis of a-chloro ketones is described, involving acylation of Grignard and organolithium reagents with N-methoxy-N-methylchloroacetamide. The efficiency of the process is further enhanced by recycling N,O-dimethylhydroxylamine.

发明人：VARIE DAVID L; VICENZI JEFFREY T; ZMIJEWSKI MILTON J
权利人:LILLY CO ELI
摘要:A process for stereoselectively forming N-substituted dihydro-2,3 benzodiazepines which are useful as AMPA receptor antagonists. The process includes an opening reduction step which sets the stereochemistry of the intermediates and the final compounds to the desired enantiomer. The reduction step may be carried out by an enzymatic reduction.
