This invention is directed to vanilloid receptor VR1 ligands. More particularly, this invention relates to hetero isonipecotic amides that are potent modulators of VR1 which are useful for the treatment and prevention of disease conditions in mammals.
Abstract A divergent intramolecular reaction of phosphine tethered alkyne in protic solvent was developed. This provided a novel and simple access to a large variety of (Z)-alkenylphosphine oxides and phospholane oxides. Our preliminary studies suggested that these divergent reactions are closely related to the reaction condition and molecular structure. A possible mechanism of C-P bond cleavage of

Chalcogen-bonded p-type semiconducting ribbons have been engineered through the self-assembly of tailored π-conjugated modules. Theoretical studies of the electronic states showed the presence of a local charge density between Te and N atoms. Implementation of the ribbons as hole-transport layers in light-emitting electrochemical cells gave rise to devices with performances similar to those obtained
硫族键合 p 型半导体带是通过定制 π 共轭模块的自组装而设计的。电子态的理论研究表明,Te 和 N 原子之间存在局部电荷密度。将带状物用作发光电化学电池中的空穴传输层,产生了性能与最先进的半导体相似的器件。

A study on the synthesis of (Z)-1,2-bis(2-bromopyridin-3-yl)ethenes, key intermediates in the preparation of 1,10-phenanthrolines, based on selective Sonogashira and Suzuki-Miyaura cross-coupling reactions has been carried out. (C) 2008 Elsevier Ltd. All rights reserved.
