commonly serve as core structures of many therapeutic agents and natural products. However, the metal-free and catalysis-free strategy for the synthesis of these privileged motifs at room temperature remains a challenging task. Herein, we report a three-component strategy to afford diverse isoxazolines and isoxazoles via [3 + 2] cycloadditions of in situ-formed nitronates and olefins/alkynes under visible-light
异恶唑啉和异恶唑通常用作许多治疗剂和天然产物的核心结构。然而,在室温下合成这些特殊基序的无金属和无催化策略仍然是一项具有挑战性的任务。在此,我们报告了一种三组分策略,通过在可见光照射下原位形成的硝基化合物和烯烃/炔烃的[3 + 2]环加成提供不同的异恶唑啉和异恶唑。
