Disclosed are compounds of Formula A: Formula A, or a salt thereof, wherein "Het", Ra, and Rb are defined herein, which have properties for blocking Nav 1.7 ion channels found in peripheral and sympathetic neurons. Also described are pharmaceutical formulations comprising the compounds of Formula A or their salts, and methods of treating neuropathic pain disorders using the same.
An efficient protocol for the asymmetric synthesis of fluorenols has been developed through an enantioconvergent process enabled by Pd(II)/chiral norbornene cooperative catalysis. This approach allows facile access to diverse functionalized chiral fluorenols with constantly excellent enantioselectivities, applying readily available racemic secondary ortho-bromobenzyl alcohols and aryl iodides as the
通过 Pd( II )/手性降冰片烯协同催化的对映收敛过程,开发了一种有效的芴醇不对称合成方案。该方法可以使用容易获得的外消旋仲邻溴苯甲醇和芳基碘化物作为起始材料,轻松获得具有持续优异的对映选择性的多种官能化手性芴醇。

The paper describes stereoselective radical aryl migration reactions from sulfur in sulfonates to aryl radicals for the synthesis of axially chiral biaryls. A chirality center in secondary benzylic sulfonates is used to diastereoselectively (atroposelectively) install a stereogenic axis via a 1,5 aryl migration reaction. Atroposelectivity has not been investigated in stereoselective radical chemistry
