The Rh(III)-catalyzed dual directing group assisted C–H activation/annulation of 3-arylisoxazolones with propargyl alcohols has been developed, which expands the application scope of isoxazolones in organic synthesis. This protocol also worked well with 3-aryl-1,4,2-dioxazol-5-ones to produce synthetically and biologically important 4-arylisoquinolones.
开发了Rh(III)催化的双导向基团辅助C-H活化/环化3-芳基异恶唑酮与炔丙醇,扩大了异恶唑酮在有机合成中的应用范围。该协议还适用于 3-芳基-1,4,2-二恶唑-5-酮,以生产具有合成和生物学重要性的 4-芳基异喹诺酮。
