A cascade oxazole-benzannulation for the synthesis of naphtho[2,3-d]oxazoles has been developed employing ortho-alkynylamidoarylketones as substrates. This procedure provides the advantage of preparing a wide variety of substituents on naphtho[2,3-d]oxazole structures. In addition, o-alkynylamidoarylketones could be prepared from easily accessible and a wide variety of commercially available starting
使用邻炔基氨基芳基酮作为底物开发了用于合成萘并[2,3- d ]恶唑的级联恶唑-苯并环化反应。该程序提供了在萘并[2,3- d ]恶唑结构上制备各种取代基的优势。此外,o-炔基氨基芳基酮可以从易于获得且种类繁多的市售起始材料制备。因此,该方法是合成具有多种取代基的萘并[2,3- d ]恶唑的明智选择。在这项工作中,证明了 27 个示例以中等到良好的收率提供所需的产品。
