subsequent cyclizations via Ullmann and Heck reactions to efficiently construct substituted 2,6-methanobenzo[b][1,5]oxazocines and 1,6-methanobenzo[c]azocines, respectively. The intramolecular Ullmann cyclization was conducted in tandem with an intermolecular arylation that enabled the rapid syntheses of a number of O-functionalized methanobenzoxazocines.
利用多组分组装工艺 (MCAP) 制备多功能中间体,这些中间体可通过 Ullmann 和 Heck 反应进行适当功能化,以便随后进行环化,从而有效构建取代的 2,6-亚甲基苯并[b][1,5]恶唑辛和 1,6-亚甲基苯并[ c ]佐辛,分别。分子内乌尔曼环化与分子间芳基化同时进行,从而能够快速合成许多O-官能化的亚甲基苯并恶唑嗪。
