rare and challenging. An intermolecular and highly enantioselective C-H arylation of relevant heteroarenes providing an efficient access to atropisomeric (hetero)biaryls is reported. The use of a Pd(0) complex equipped with H8-BINAPO as chiral ligand enables the direct functionalization of a broad range of 1,2,3-triazoles and pyrazoles in excellent yields and selectivities of up to 97.5:2.5 er. The
阻转异构(杂)联芳基是在配体、天然产物和生物活性分子中越来越重要的基序。通过有效的 CH 功能化方法直接构建立体轴非常罕见且具有挑战性。据报道,相关杂芳烃的分子间和高度对映选择性 CH 芳基化提供了对阻转异构(杂)二芳基的有效途径。使用配备有 H8-BINAPO 作为手性配体的 Pd(0) 配合物能够以高达 97.5:2.5 er 的优异产率和选择性直接官能化范围广泛的 1,2,3-三唑和吡唑。该方法还允许 atroposelective 双 CH 芳基化,用于构建两个具有 >99.5:0.5 er 的立体轴。

A palladium-catalyzeddomino Heck/intermolecular direct hetero arylation sequence of unactivated alkenes was developed, providing 1,2,3-triazole containing bisheterocycles bearing all-carbon quaternary centers with yields of 25–90%. The protocol was extended to 1,3,4-oxadiazoles as well. The installed triazole was further exploited for late-stage functionalizations, and the mechanistic studies indicate
A series of novel bis(NHC) Cu(i) catalysts enables the production of triazoles with different substitution patterns and bioconjugation via “click” chemistry under homogeneous and/or heterogeneous catalytic conditions in aqueous media.
