HCVNS5Ainhibitors have demonstrated impressive in vitro potency profiles in HCV replicon assays and robust HCV RNA titer reduction in the clinic making them attractive components for inclusion in an all oral fixed dose combination regimen for the treatment of HCV infection. Herein we describe our continued research efforts around the alkyl “Z group” modification of the tetracyclic indole-based NS5A

electrooxidation of a solvent (e.g., DMF)-ligated B2cat2 complex, whereby a solvent-stabilized boryl radical is formed via quasi-homolytic cleavage of the B−Bbond in a DMF-ligated B2cat2 radical cation. Furthermore, a strategy for the electrochemical gem-diborylation of gem-bromides viapairedelectrolysis is developed for the first time, affording a range of versatile gem-diborylalkanes.
该报告描述了溶剂(例如 DMF)连接的 B 2 cat 2络合物前所未有的电氧化,由此通过 DMF 连接的 B 2 cat中B−B 键的准均裂裂解形成溶剂稳定的硼基自由基2自由基阳离子。此外,首次开发了一种通过配对电解对宝石-溴化物进行电化学宝石-二硼基化的策略,提供了一系列通用的宝石-二硼基烷烃。
