The present disclosure provides certain tetrazole derivatives that are inhibitors of transient receptor potential ankyrin 1 (TRPA1), and are therefore useful for the treatment of diseases treatable by inhibition of TRPA1. Also provided are pharmaceutical compositions containing the same, and processes for preparing said compounds.

10-bis(1,5-diphenylpenta-1,4-diyn-3-ylidene)-9,10-dihydroanthracenes (BDPPD-DHAs) carrying polar organic functional groups was synthesized through Sonogashira cross-coupling reactions. The structural and electronic properties of these BDPPD-DHA derivatives were investigated by single crystalX-raydiffraction, UV-Vis absorption, and fluorescence spectroscopic analyses. It was found that the incorporation
A palladium mediated synthesis of a common synthon for the syntheses of antioxidantanalogues of naturally occurring salvianolic acids is presented. The synthetic route may be used to obtain analogues with a balanced lipophilicity/hydrophilicity which may result in potentially interesting LDL antioxidants for the prevention of cardiovascular diseases.

Vinyl carbocations were generated via single-electron oxidation of alkenyl boronates using electrical potentials. This electrochemical process enabled the formation of these reactive species without the use of Lewis or Brønsted acids. The intermediate vinyl carbocations were trapped with nucleophilic fluoride sources to yield vinyl fluorides; the production of new C−C, C−Cl, and C−Br bonds was also
乙烯基碳阳离子是通过使用电位对烯基硼酸盐进行单电子氧化而产生的。这种电化学过程能够在不使用 Lewis 或 Brønsted 酸的情况下形成这些反应性物质。中间乙烯基碳阳离子被亲核氟化物源捕获以产生氟乙烯;还证明了新的 C-C、C-Cl 和 C-Br 键的产生。
