A finely tunable chemoselectivity in arylation of 3-aryl-1,2,4-oxadiazolones with ortho-(trimethylsilyl)phenyl triflates is reported, including silver-catalysed O-arylation and metal-free N-arylation.
Despite their tremendous synthetic and pharmaceutical utility, primary azaaromatic amines remain elusive for access based on a generally applicable C–H functionalization strategy. An oxadiazolone-enabled approach is reported for convenient entry into N-unsubstituted 1-aminoisoquinolines through Co(III)-catalyzed redox-neutral, step-, atom-, and purification-economic C–H functionalization with alkynes

A Cobalt‐catalyzedannulation of 3‐aryl‐1,2,4‐oxadiazolones with 1,3‐diynes has been developed, in which reaction temperature variation considerably affects the cyclization orientation and afforded structurely distinctive products in good yields and high regioselectivity. Additionally, the late‐stage transformation of the cyclization products into N‐containing heterocycles is also demonstrated.

Here, we report the method for copper-catalyzed N-arylation of diverse oxadiazolones by diaryliodoniumsalts under mild conditions in high yields (up to 92%) using available CuI as a catalyst. The developed method allows utilizing both symmetric and unsymmetric diaryliodoniumsalts bearing auxiliary groups such as 2,4,6-trimethoxyphenyl (TMP). We found that the steric effects in aryl moieties determined
在这里,我们报告了使用可用的 CuI 作为催化剂在温和条件下以高产率(高达 92%)通过二芳基碘盐对不同恶二唑酮进行铜催化 N-芳基化的方法。所开发的方法允许使用带有辅助基团(例如 2,4,6-三甲氧基苯基 (TMP))的对称和不对称二芳基碘盐。我们发现芳基部分的空间效应决定了 1,2,4-oxadiazol-5(4 H )-ones的 N-和 O-芳基化的化学选择性。甲基取代的二芳基碘盐显示出作为选择性芳基化试剂的巨大潜力。结构研究表明 1,2,4-oxadiazol-5(4 H)-对空间位阻二芳基碘鎓盐的芳基化的影响。还证明了所提出方法的合成应用对 1,3,4-恶二唑-2(3 H )-酮和 1,2,4-恶二唑-5-硫醇的选择性芳基化。
